I've been able to get it to work both with and without video drivers installed on my Athlon XP. I will say that the Pentium M only supports up to SSE2 though.

Huh. That's strange. The Pentium M certainly supports SSE. I'm not sure if this has any impact or not, but I have KernelEX installed on my own Windows 98 machine. Though the files do normally work fine without it, maybe it could help?

What hardware are you trying to run it on? It mentions that even the most basic softpipe implementation requires a Pentium II to run, meaning you'll need at minimum i686 compatibility. I can confirm that it works fine on Windows 98 and an AMD Athlon XP, which has i686 compatibility and SSE extensions.
