kdrive porting question

Hello,

   As a first forray into the graphics programming, I have started porting
the neomagic driver from xizzle to kdrive. So far, the driver can detect
the chip and map the framebuffer and MMIO stuff. I'm a bit confused about
how ScreenInit is supposed to work.

Looking at how other drivers get screen information, some such as the ati
and mga drivers get info using vesa or fbdev, but the i810 driver seems to
get screen information itself. What should I do? The xizzle neomagic
driver claims to get information from the 'framebuffer layer's
ScreenInit function', but is this the same as getting information from
fbdev?

Also, can I put the work-in-progress driver into CVS, or should I wait
until it is functional before submitting? I hate to clutter the CVS
changelogs, but it would be nice to have some version control.
