How much is this going to matter for older video chipsets tho?  My
Thinkpad 390X has a Neomagic 256AV chipset with 2.5MB VRAM.  It's not
like that's going to support any fancy graphics.  I'm not against it
so long as I can TURN IT OFF, which is something that the KDE4 devs
can't seem to understand.

Which chipsets?  The ATI Mobility M3(Rage128 Based)?  Or
Radeon/GeForce and higher?

As for Amarok, I don't use it.  MPlayer is my media player.  A Qt port
of Firefox would be great tho........

Not an issue so long as it's maintained IMO.

Will do.  Thanx
