I went ahead and tried to file an upstream bug at bugzilla but apparently this bug has previously been reported and fixed. Anydoby interested can go and read the link below. https://bugs.freedesktop.org/show_bug.cgi?id=34457
Basically this is what you have to do. QUOTE "Either upgrade your system to Ubuntu Oneiric or install the fixed kernel (with backported kernel patches) from Launchpad PPA for Ubuntu Maverick. Both solutions will fix the problem, as it did for the others having this special buggy chipset." END OF QUOTE.
