Guys, did all these things get fixed up in 2.6.12-rc5?

At least I don't see the fix we discussed with Jim included. I'll 
test-boot tomorrow. Anyway, I seem to be the only one affected, and 
switching CONFIG_FB_PM2_FIFO_DISCONNECT fixes the problem, so, maybe we 
could just mark this option "dangerous".

Will (try to) add tomorrow.

Confirmed - with CONFIG_FB_PM2_FIFO_DISCONNECT fb is still orange, without 
- no problem.

Quick summary from my point of view: Guennadi is the only report of this
problem, though equally he's the only user I know with an Elsa AG GLoria
Synergy. I have not yet managed to work out why this could be happening; I had
expected that disabling the card reset that pm2fb does on initialisation would
fix matters, leaving the card at its BIOS initialised state. But it doesn't,
and sees to cause bad problems.

PM2_FIFO_DISCONNECT doesn't seem to me to bring much to the party. Since we now
have an example of it causing breakage, I agree with Guennadi that it should be
marked 'dangerous'. I've been away from home/internet connection for some time;
I'm back on Tuesday and I'll submit a patch to do that ASAP.
