Guennadi, could you please confirm that

12-rc1-mm1/broken-out/pm2fb-x-and-vt-switching-crash-fix.patch

fixes this one?

As discussed with Jim on linux-fbdev-devel this patch fixes the vt / X 
switching problem. We still don't know why starting with 2.4.11 I have to 
switch CONFIG_FB_PM2_FIFO_DISCONNECT off to restore colours / images.

I traced this breakage down to the patch to 
pm2fb.c after 2.6.10-rc2. Jim wanted to try to reproduce this problem with 
my fb-geometry / colour settings, but I haven't heard from him since then, 

FIrst off, so we're all clear, the problem with vt/X switching was definitely a
pm2fb bug exposed by chages in fbcon, and is definitely fixed by the above
patch. Please apply.

As to Guennadi's problem with colours and images, I've been trying to
reproduce locally without success, hence silence. My pm2fb-on-Sparc
correspondent hasn't seen this either, and I've had no other reports.

I have one possible clue, which I'll pursue with Guennadi off-list.
