fglrx will do on r300. I'm wondering about that though a bit, that would be 11.3 bit for coords or so ;-). It would also mean the tiling regs need to be different a bit on r300 compared to r100/r200.
I looked through the register manual for Radeons and it looks like the did away with most of the tiling registers and options. For example, I don't think they have SURFACEx registers anymore - just a choice of tiling size, enable/disable and a "super-tiling" - probably used for multi-core rendering.
Of course, it might be the relevant registers just aren't there.
Actually, the other day I asked Aapo on irc to dump these regs with fglrx, and they seem to be used on his card (and have perfectly good looking values, i.e LOWER, UPPER, the pitch and the surface tiling type all seem correct).
