It can't, but I don't mind communicating by e-mail and updating the
tracker afterwards if you'd prefer.

I've tried with a VX800 laptop with CRT+panel, and the 1.5 board with
CRT, and neither worked. The fb init does not complete:
[ 24.128168] vmap allocation for size 268439552 failed: use vmalloc=<size> to increase size.
[ 24.136654] ioremap of fbmem failed
[ 24.140759] viafb: probe of 0000:00:01.0 failed with error -5
It looks like it's trying to do DVI/panel output even though I only
had CRT connected, in this case (see the dmesg posted in the bug).
I'll look into it a little more, just wanted to give you a heads-up.

That's fine, thanks for looking at it. It's not on the critical path,
so no rush.
