6.2.1 .xsession-errors

[mecho]

I am using 6.2 and I have to major trouble makers - adobe flash and alsa when a game is played. I tackled the problem with flash by starting iceweasel using a small script.
nohup iceweasel 1>/dev/null 2>&1 &
I made my desktop file to point to shell script containing the above command and I no longer have error messages.
Another frequent error in xssession-errors is atk-bridge-WARNING
I fixed that by disabling accessibility in gconf,
gconftool-2 -s --type=bool /desktop/gnome/interface/accessibility false

If anyone has a solution to the alsa errors during game play, I will be very thankful
