Yet another confirmation with AMD Radeon HD 6470M on Dell Vostro 3350

lspci | grep -i radeon
01:00.0 VGA compatible controller: ATI Technologies Inc NI Seymour [AMD Radeon HD 6470M] (rev ff)

uname -a
2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:24 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

bin$ cat /etc/issue
Ubuntu 11.04 \n \l

I noticed that changing power supply and non powersupply mode triggers this more frequent.
But having this laptop for one week I dont really se the pattern.
Do the radeon remember that it should sort of resume the card??

Now I have blacklisted both radeon and fglrx and I seem to be able to boot with less struggle.
In /etc/rc.local I modprobe the radeon and run switchero. Most of the time fan goes of; but sometime I have to run the switchero command in my gnome-session.
