Well, this is unlike most users of Twin Turbo cards, if the past list
traffic is any measure. Interestingly, I have seen comments before
that the issue is not the imsttfb driver, but X itself. This would
not be inconsistent with your setup, given the debian X. I would love
to get the twin turbo working, I have been waiting for X4 to get far
enough along, but it appears to still be lacking in even
straightforward atyfb support (debugged that is), as per the last I
read. Older ATI Rage Pro card(s) are what else I have, but it won't
do me any good to get one card working if another that I have breaks.

From a kterm 5 seconds ago:

Of course, the actual dotclock is really only 105.336 MHz (1280x1024x75Hz),
but the modeline works. 1280x1024x96Hz would be nice, mind you, but I don't
quite think my monitor could take it. ;)

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:

I'm not sure how much I can elaborate on it, since I've never actually
managed to get it to not work.

And that's about it. I'm booting with BootX, by the way.
