X does it on the cards using VM86 mode. X is a user
space app. I want to do it from the framebuffer device
driver. VM86 mode is not accessible from a device
driver.

I have a user space app (500K) that does the reset.
Non-86 platforms are forced to use an x86 emulator to
reset the card. X Windows has an X86 emulator embedded
in it for this purpose. It is just so pointless
carrying around and maintaining tens of thousands of
lines of code simply to reset video cards.

We can add the same reset code to X and get rid of the
real mode emulation for the ATI cards too.

There are many variations (50?) of the Rage128
hardware. Desktop, mobile, TV tuner, US, European, TV
OUT, DVI, etc. I would need one of each to do the
reverse engineering.
