3.2.0. That one doesn't have my cirrusfb probe rewrite and fixes?
You need at least 3.3 for that.

Sorry, can't parse that sentence, esp. the second "doesn't".

Amifb supports both "vga" and "pal-lace".
For cirrusfb, you can use the whole standard video mode database.

What's the last kernel version that worked? Bisection?
Does it work if you update drivers/video/cirrusfb.c to the latest version?

For the record, I don't have any Cirrus hardware.
