Suggestion:

A.  Common to all:

Hardware:
1. color depths and color visuals supported
2. can the driver pan on the y-axis?
3. can the driver pan on the x-axis?
4. can the hardware state be changed (ie with fbset)?
5. access to framebuffer (fb_read/fb_write/mmap)
6. access to MMIO space

Console:
1. can it accelerate imageblit (font drawing)
2. can it accelerate copyarea (block transfers)
3. can it accelerate fillrect (block sets)

Video Mode setting:
1. How is the video mode set (more than 1 can be chosen)?
	a. at driver load
	b. user-specified modelines (ie. fbset)
	c. global mode database
	d. EDID/private mode database
	e. EDID/GTF calculation
	f. driver-specific method

B. Miscellaneous:
	a. support for interrupts on vsync/vblank
	b. ioctl for vsync/vblank
