At the time, we were using XFree86 4.0.1, which had a
problem supporting acceleration features in the Radeon's ATI S2464
chipset, especially when used on very fast-CPU systems. Fixing that
required a one-line patch supplied by Darryl Straus. I'm pretty certain
that XFree86 4.1.0 includes the patch.[1]
To correct what I said earlier: With the SB Live card, you'll want
kernel 2.4.8 + patches or later, not 2.4.6 + patches. That's what I
get for writing from memory.
A few other tweaks proved also necessary: Enable "Use PCI Interrupt
Entries In MP Table" in the motherboard BIOS, and pass the booting Linux
kernel the "noapic" parameter to keep the AMD766 north-bridge chip
out of APIC mode, which can cause hangs.
[1] Or use this, if you're stuck with XFree86 4.0.1, and don't mind
recompiling:
