Note however that the direct acceleration you get using matroxfb
is 4-6 times faster that the ioctl() based acceleration of the Matrox
KGIcon driver. On a related note - direct acceleration using KGIcon
is also about 50% slower than direct acceleration using matroxfb,
so something must be broken with our mmap() handler.
