Yes, for a while I was tracking its CVS and rebuilding often. I had
3D and video working together just fine under 2.4. Gentoo Linux even
went as far as making a drm-kernel ebuild that patched for gatos.
:pserver:[EMAIL PROTECTED]:/cvsroot/gatos
module drm-kernel

No. I2C, so far as I know, isn't involved at all.

They have an ati.2 module (same CVSROOT) that you xmkmf against a
compiled XFree tree, then make ; make install, that provides access to
the tuner and v4l playback (MPEG acceleration). A separate kernel module
is required for video capture.
The ati.2 module replaces
/usr/X11R6/lib/modules/drivers/{ati,atimisc,r128,radeon}_drv.o
and adds
/usr/X11R6/lib/modules/multimedia/{bt829,fil236,msp3430,saa7114,tda8425,tda9850,tda9886,theatre}_drv.o
