Re: XF68_FBDev under MkLinux?

[Elgin Lee <ehl@funghi.com>]

Geert--

Recent (non-official) MkLinux kernels support /dev/adbmouse (busmouse
emulation).  GPM works with it, so I suspect that XF68_FBdev would as
well.  Choice #2 does seem the least amount of work.

One question--would acceleration would still require framebuffer
devices?
