2.6.13-rc2-mm2 -- vesafb mode and mtrr questions

I am using Grub and have this in my kernel arguments:
video=vesafb:ywrap,mtrr,vram:128 vga=792

I have a 1280x768 laptop display.

My Xorg.log contains:

(II) I810(0): VESA VBE PanelID read successfully
(II) I810(0): PanelID returned panel resolution : 1280x768
(II) I810(0): VESA VBE DDC supported
(II) I810(0): VESA VBE DDC Level 2
*Mode: 7e (1280x768)
        BitsPerPixel: 32

Does this mean there is a way for me to tell vesafb to use this mode?
I would like to have the consoles display in 1280x768.

Also, when I boot I see that there are problems with overlapping
mtrr regions.  I have read:
http://www.rage3d.com/board/showthread.php?t=33821469
but this doesn't give me enough information to understand my
current mtrr configuration:

cat /proc/mtrr
reg00: base=0x00000000 (   0MB), size=1024MB: write-back, count=1
reg01: base=0x3df00000 ( 991MB), size=   1MB: uncachable, count=1
reg02: base=0x3e000000 ( 992MB), size=  32MB: uncachable, count=1
reg03: base=0xe8000000 (3712MB), size=  16MB: write-combining, count=1

I only have 1Gig of RAM, so I don't know what this 3712MB could be 
refering to.

The system information says the video card has access to 128M of memory,
yet my Xorg log doesn't say that is getting used:

(**) I810(0): page flipping disabled
(==) I810(0): Display is using Pipe B
(--) I810(0): Maximum frambuffer space: 32600 kByte

What is going on?

How do I best optimize my vesafb and Xorg configurations?
