that's what I supposed, and I didn't notice problems on my laptop so
far, either (which may be due to the fact that I only use it for
software development; no audio, no nothing).

On second thought, this may not be necessary: my colleague didn't
extract the patches from GDM 2.20, but took them from the
opensolaris.org JDS repository. I don't know what license they are
under there (CDDL maybe), but even if they were GPL only, Sun/Oracle as
the copyright owner could easily double-license them under GPL and MIT
license or whatever Xorg requires these days, to avoid reimplementing
(if not reinventing) the wheel.

Will do. The incentive for us, apart from being good OpenSource
citizens, is avoiding the need to maintain our local version of xdm
forever :-)
