Yep. Two instances of mprime installed in seperate directories.
System is dual PII-350 in a Supermicro P6DBS board running kernel
2.2.12-20smp (straight from the Red Hat 6.1 CD). As a matter of
principle I run these under a normal user account, not root, and use
"nice -n20" to control the job priority.

Nope. Starting/stopping/reconfiguring X has no effect except to make
the mprime processes run more slowly. My system has an ATI Xpert@Work
AGP graphics card. Basically I just installed X from the distribution
CD (along with everything else), it seems to work fine ... BTW I now
have Gnome installed but not KDE, this is the default for Red Hat
distributions these days. Can't see that this should be a problem,
though.
A "top end" graphics card like the Rage128 is likely to use an
interrupt for the graphics. This may interfere with any interrupt
used by whatever you have in PCI slot 1 (or sometimes some of the
higher PCI slots as well). Interference here might well cause
problems which could manifest themselves as "illegal sumout". Try
swapping around the PCI cards so that those that can't share
interrupts don't have to do so. In fact, I find, as a rule of thumb,
if you have an AGP graphics card installed then don't use PCI slot 1
or any other PCI slot which shares an interrupt with AGP.
This advice applies wholly irrespective of operating system!
