Thanks for the tip.  I'll check for Direct Framebuffer in the BIOS.
What is MTRR?  I catted /proc/mtrr and see the entries below but have
no idea what they mean.

jdale at jdale-myth:~$ cat /proc/mtrr
reg00: base=0x00000000 (   0MB), size= 512MB: write-back, count=1
reg01: base=0x20000000 ( 512MB), size= 256MB: write-back, count=1
reg02: base=0x30000000 ( 768MB), size= 128MB: write-back, count=1
reg03: base=0xa0000000 (2560MB), size= 128MB: write-combining, count=1
