Changing the Bios setting from 1 MB to 8 MB as suggested by Miguel Figueiredo did NOT fix this on a Dell Dimension 2400
Changing the setting from vga=788 to vga=normal seemed to do the trick.
This was a fresh install with Wheezy RC1 i386
Now tyring to figure out why the Dell keeps crashing with a kernel panic. Seperate issue...
