FC5t3 issues with nv6800GS and NVRAID

[Dan]

I tried to install FC5t3 but graphical install had issues, and seeing as 
my FC4 dvd also seems to have these issues I believe it is because of 
the nvidia 6800GS pci-express video card I recently upgraded to, since 
installing FC5t2 successfully (but not being able to boot it; that is 
the other issue).
So I installed in text mode, though it was having problems displaying 
the text (everything would move one character to the right when 
selected, leaving characters all over the place, so it just was 
extremely hard to figure out what i was doing). I installed successfully 
to NVRAID 0 as with FC5t2, but as it was in such a confusing mode I 
couldn't tell how the bootloader was attempted to be installed. I 
believe I told it to install to the correct drive, though. However, upon 
boot, it didn't even get as far as FC5t2; it just comes up with GRUB 
Geom Error. Trying to install grub from rescue mode also results in 
failure; setting it up goes smoothly but upon the setup command, it 
can't find the appropriate partition for some reason; it gets all the 
way to "install /grub/stage1 (hd0) (hd0)1+15 p (hd0,1)/grub/stage2 
/grub/grub.conf" and fails, Error 22: No such partition. Now I'm going 
to have to install FC5t2 or FC4 so I can boot back into windows and 
continue using this computer for a while.
