I have a Tyan Tiger 133 dual P3 motherboard based on the via 694 
chipset and I have not had any problems with it running in SMP mode 
except for one.  If I run two instances of dnetc and then start up 
xmms the machine will eventually hang solid.  Sometimes it takes a few 
minutes, other times a few hours, but once it hangs, nothing short of 
power cycling it will bring it back.  I've been tracking -STABLE with 
this box for about 4 months, and have had the problem all along.  I 
posted it to this list and it was described as a priority inversion 
problem causing deadlocks.  Aside from this issue, the box is rock 
solid, it has been up for well over a month, often times with two 
copies of dnetc running the whole time.  

FWIW, I'm running two p3-600b/133 cpus, two 256 meg pc133 crucial 
SDRAMS, WD 30 gig ata/66 IDE disk, and a linksys LNE100TX nic.
I can attach all sorts of stuff like a dmesg, or output from a verbose 
boot wor whatever if someone wants it.
