2.6.32 with pci=nomsi:

It's "bad". irq # 19 count is frozen. glxgears draws, but the FPS is reduced
70, while without "nomsi" it was 240. Xorg log is the same. dmesg is same
except "irq for nomsi".

I haven't reported this before, but when it's "bad", redraw of my x terminal,
urxvt, is snail-slow, and I saw it with "nomsi", too. (I don't need opengl, so
this is the biggest trouble for me.)

3.0.4: no much difference with pci=nomsi, it's anyway bad. (In 2.6.39 and
3.0.4, in most cases glxgears is not drawn, showing only black box. But in
2.6.32, every time I tried gears were drawn even with nomsi, but the test is
not thorough.)

Most of dmesg differences are trivial, but I quote one hunk here FYI:
