On my Sony Vaio YB laptop running the dev branch for Ubuntu Oneiric, I
get a backlight flicker after the computer wakes from Suspend.  The
flickering seems to subside after 10-15 minutes, but even rebooting does
not fix the flickering.  (in fact, once triggered from ubuntu, the
flickering will happen in the BIOS menu)  I know this is not a hardware
problem, because the same problem does not occur in Windows.  I imagine
it's a driver problem, though the flickering happens whether I use the
radeon or fglrx driver.
