Matt,

well, it does. During initialization (see vesa_bios_init() in vesa.c) it 
reads adapter and video mode information using bios calls 0x4f00 and 0x4f01.

IIRC the "mad system timer" issue was never triggered by this 
initialization (but instead by video mode switching). But if you're 
worried, just leave VESA out and put only SC_PIXEL_MODE and (if you 
like) VGA_WIDTH90 in GENERIC because vesa can be kldload'ed later.
