I would suggest leaving pre-avivo cards and IGP chips at the BAR location, for r5xx/r6xx/r7xx discrete cards, put it at 0. Although I guess Dave had a problematic laptop with the backlight control. Did the VGA disable stuff fix that or does it still need to have VRAM at the BAR location? Maybe some bios scratch reg magic if it's still a problem. Also, FWIW, RS600 and RS690/RS740 have two sets of fb_location regs, MC_FB_LOCATION and NB_FB_LOCATION. I think the latter is probably the equivalent of the TOM register on the old chips.
