Fedora 12 is what's currently available, from a previous ARM port 
effort.  It's not supported anymore.  The ARM SIG is targeting F13 (now 
bootable: 
http://paulfedora.wordpress.com/2010/12/15/fedora-13-arm-alpha-root-file-system/) 
and onward.

I think the plan is to eventually get ARM kernels based on the Fedora 
kernel sources built for many different development boards.  Currently, 
all effort is focused on getting the F13 package collection built.  Your 
efforts would certainly be welcome should you try to tackle kernel builds.

I'll also note that the latest F13 koji builds are already available in 
a repo: http://arm.koji.fedoraproject.org/repos/dist-f13-build/latest/  
That's the repo that was used to generate the F13 rootfs.  As packages 
are built, this repo should approach the coverage of the primary 
architectures' repositories.

Ubuntu and Debian have been working on this for a much longer time.  The 
current Fedora effort is only several months old, and builds off of the 
incomplete F12 package collection.  Further, we only got F13's gcc and 
glibc working on ARM two months ago, which held up pretty much all 
progress.  Most of the big problems have been knocked out, and things 
are indeed progressing.  I don't really understand the pessimism, my 
perception is that things are going quite well (it's taken under two 
months to get a working F13 rootfs!)  I don't think that ARM fedora is 
being neglected at all, it's just a young effort and the results aren't 
immediately apparent yet.

Alpha-quality rootfs is available for you to play with: see above.  krb5 
can be built without OpenSSL for bootstraping, the option is at the top 
of the krb5 specfile.  Several packages need to be bootstrapped in a 
similar fashion: Mono requires mono-devel for instance.

I guess nobody has addressed this yet; most of the build errors thus far 
have been fixed over IRC or through the list.  There is, however, a 
"bugzilla" product in the redhat bugzilla where you can file bugs 
against the redhat 
bugzilla.<http://fedoraproject.org/wiki/Architectures/ARM/Package_Maintainers>

Luckily, this is already happening on the ARM koji for F13 and beyond.  
There's a status page at http://arm.koji.fedoraproject.org/status/  It 
might be easier to look for build failures there to fix than to 
duplicate the effort (it's certainly faster).  You could either set up a 
mock config to build locally, or just install the f13 rootfs.

There are plans to add some pandaboards to the koji buildfarm as well:

Maybe set mock up to work off of a USB hard drive on the Sheeva (if you 
have one laying around?)

The web interface seems broken at the moment, but it's still possible to 
submit builds via the command line using directions at 
http://fedoraproject.org/wiki/Architectures/ARM/Package_Maintainers.  I 
just submitted a scratch build without issue.

Give it time, F13 and beyond are striving to reach package parity with 
the primary architectures (as much as is possible anyway.)  The effort 
is young, but making lots of progress.
