However, I still get a minor problem with the driver.
When I switch between the default 640x480-60 mode and 1024x768-85 mode
the 1024x768 gets interlaced, with completely different timings. I have
to use fbset to restore it to 1024x768-85.

I think this is a `feature' of the new mode selection code. When I tried
booting my Radeon with `1024x768@100', I got 87 Hz interlaced...

Michal's problem is more of a failure to preserve the per-display var, which
should be fixed with recent mm or rc kernels.

Yours is more of boot mode selection problem and most drivers use
fb_find_mode() for that.  The default modedb does not have 1024x768@100
non-interlaced, so it passed the interlaced version to the driver, which it
happily accepted.  Thus, you get the interlaced version.

Modedb does have that mode! Before I've been using it for years on my PPC box.
