Thanks Phil.  The corruption of /dev was the issue (I suspect that it
may have been part of JACK's problem as well).  Once I managed to get
the rpm for dev onto the machine (#$%@!#@! rescue boot from FC1 disk 1 
doesn't actually mount the CD itself.  Or even create /dev/hdc so you
can manually mount it), one rpm -i --force later and the problem was
solved. 

I think I'll keep that RPM on my machine handy for now :)

I'll run memtest x86 soon & let you know the result.

Now back to the problem of why fluidsynth won't connect to JACK . . .
