This system' OS has been upgraded to Lucid ... and now uses different
drivers (viafb and vt8623bf) instead of openchrome.

The above drivers seem to have solved problems with this particular
chipset, for me at least. Switching to consoles tty displays with ctl-
alt-F6 etc works fine.
I just re-checked this bug report because I have another system with the
same motherboard and chipset in which I have installed Gento, and
haven't been able to get Openchrome to work in that; but Gentoo doesn't
have the vg8623 and viafb drivers. (This is a different VIA chipset from
the one in bug #495553.)
