Interesting suggestion. Well, KInfocenter tells me that the 3D accelerator
is by Intel: "4 Series Chipset Integrated Graphics Controller". The driver
is by Tungsten Graphics and the renderer is "Mesa DRI Intel Q45/Q43 GEM
20100330 Development [hmm...] x86/MMX/SSE2". I run the OS from one WD HDD
on SATA. Processor is Intel E8400.
