Could you elaborate on that? I have an IMSTT 128 (2Mb VRAM) and I'm
unable to accelerated video on a plain pmac kernel. I am currently stuck
at kernel 2.2.12 because this is the only kernel that will accept a
patch from Ryen Nielsen (http://krazynet.com/~ran/linux/imsttfb.c).
The last pmac I tried is 2.2.16

Here's some info about my system:
