Re: [OPENBSD] X doesn't seem to work (fwd)

You need to use the XFree86 aperture driver.  The following from
your output is the clue:

(--) checkDevMem: warning: failed to open /dev/mem and /dev/xf86
        (No such file or directory)
        linear framebuffer access unavailable
The mach64 X server requires at least a 4Mb memory aperture.

Otherwise the server cannot twiddle the card's naughty bits.
This should just be a matter of uncommenting a line from the
relevant rc file (rc.securelevel probably).
