I guess Thomas is the right person to answer that. I recall some things
could not be done because of the lack of documentation on the card. I guess
some modes don't work because there is not enough st_memory allocated in the
default kernel.

I think this is indeed correct. I'll add this to the FAQ.

The slack should be multiplied by the number of virtual consoles. It is there
because the planes should be aligned on a page (8Kb) boundary to supply
mmap-calls. This means that you should add 8Kb to the above results.
