HP zv5000z AMD64 Development Install fails

[Brian Stretch]

I was able to get FC1 AMD64 to install on this HP zv5000z Athlon 64
nForce3 chipset notebook, but it locked up on reboot with the capslock
light blinking, possibly didn't read the GeForce 440 Go vidcard right? 
The lockup was right about the time it ought to switch to X.  I did a
graphical install, no need for textmode, though the screen did go
out-of-sync for a few seconds at the tail end of the shutdown-to-reboot. 

The AMD64 devel tree from today and yesterday didn't get very
far.  I tried a NFS install from a local mirror of the duke mirror.  Fedora
says "no valid devices were found on which to create new file systems"
after I select manual partitioning with Disk Druid.  Then it reboots.  
I tried acpi=off selinux=0 just for laughs, no diff.  Anyone have any 
ideas before I bugzilla this? 

It can't detect the "mouse" either, which is an ALPS keypad, and I
didn't see an option to manually select it like I could with FC1. 

BTW: I discovered a SERIOUS flaw in the zv5000z.  If you try to use
both SODIMM slots you'll get memory corruption errors.  See here:
