--- Comment #11 from Jörg Höhle hoehle@users.sourceforge.net 2009-04-23 07:42:24 --- CMR2's package cover (published 2000 approx.) lists these supported HW devices: 3Dfx, Voodoo2, Voodoo Banshee, Voodoo3, Voodoo5, 3DLabs Permedia 3, ATI Rage Pro, Rage 128, Intel i740, Matrox G100, G200, G400, NVidia Riva 128, Riva TNT, Riva TNT2, GeForce 256, GeForce 2, S3 Savage 4, Savage 2000. 3D with 8MB RAM, 233MHz, D3DX7.0a.
I don't know whether they all support(ed) S3TC or whether CMR2 may contain alternate code path not using DXT textures. Note that i740 is supported, an ancestor of i915.
(Although I now have s3tc enabled in /etc/drirc, it's clear to me it's not a completely satisfying solution. E.g. from what Scheidegger writes, I would get into trouble if I wanted to use QuakeIII or DoomIII. But that's as far as one can currently go without too much hassle.)
