it's right, 4k page size

Just a curiosity, i've only two powerpc machines[1] equipped with PCIE
videocards and both them are not able to boot with radeonkms.
Modern PCI-E videocards are not recognized by the old linux framebuffer
subsystem and they solely can be managed by the new KMS frame buffer
that doesn't work properly on Power Architecture. Anyway, YDL
Powerstation can fallback to use the old OpenFirmware
frame buffer.
KMS porting to Power Architecture machines with PCIE is it only an
exercise or someone is also able to test them?
Because i can understand that the userbase is non-existent and the
dri-developers don't have these "rare" machines.
