I don't think they have to do even that...
Well, there is another way, aparantly:
If they make drivers that link with the Y server, they must release them
under the GPL or not at all (score one for those of us running GNU/Linux
on anything other than x86, and another for us GPL "nuts" ). If they
free their drivers, I would gladly volunteer to write a graphical
installer if only because I would be in such a good mood.
If, on the other hand, they link with the client, (I'm sorry to say I
don't yet know enough about how Y works either to know which case would
apply) they will be able to release the drivers as .o files.
I'm glad the Y server is GPL, it'll make it at least a small bit tougher for the video card manufacturers release non-free video drivers.
I'm fecking sick of non-free video drivers. Neither ATi or Nvidia have free (as in freedom, as usual) drivers, and at that, I can't play any half modern 3d games.
Anyone know which other video card manufacturers release free drivers? I know 3dfx used to (they were at least open-source, not sure if they qualify as free software (by GNUs definition)).
