This one is interesting as I'm currently running the windows drivers
under ndiswrapper, and its working fine. But I would like to be able
to junk the ndiswrapper thing if I could.

I agree, but here is my conundrum: When I try to install the x86-64
from the dvd on an HP lappy with an AMD64 Turion in it, the
installation takes a dump right after formatting the partitions because
it cannot find setup-2.5.49 on the dvd. I tried twice, with two
diferent dvd, on a +R and one a -R. Now I just looked at the dvd, and
I was able to unpack and view the contents of this file with mc with no
So the $32k question is what happened? Do I need to add more options to
the boot line in order for it to work? I'm currently booting the x86
install using "irqpoll noapic nopapci pci=assign-busses lapic".
Or is there a way to convert an x86 install to an x86-64 install on the
fly? I'd hate to have to redo all the customization I've put into this
at this late date when I have only about 4 days to do it in.

People having trouble with vz bouncing email to me should add the word
'online' between the 'verizon', and the dot which bypasses vz's
stupid bounce rules. I do use spamassassin too. :-)
