23 On the guest, I unmerged xorg-server and tried emerging
24 xf86-video-modesetting. The result was that it would've pulled in
25 xorg-server, which would again have blocked xf86-video-modesetting.
26 Wierd.

45 As I mentioned earlier vmware, cirrus, and bochs all ticked off in
46 "make menuconfig". Now that I have something working, I think I'll make
47 a copy of the 10-gig guest disk image before any further tweaking that
48 might render it inoperative again.

53 I've tried that earlier, when things weren't working. Maybe it'll
54 work this time.
