Sort of. It looks like your Radeon card is a PCI card, and your SiS
card is AGP. I don't think that DRI works with PCI Radeon cards at
all, so that's out (don't take my word for it, though: check
dri.sourceforge.net). The best I can tell you if you want DRI is
check if that SiS chip is supported by DRI and if it is, reconfigure X
to use that card instead.
Hope this helps,
Lucas
