 As the error message above states, "the namelist argument supplied
 is a debuginfo file, which must be accompanied by the kernel file from
 which it was derived".
 
  crash -d255 System.map-2.4.21-47.0.1.ELhugemem /vmware/vmcore \
     ./usr/lib/debug/boot/vmlinux-2.4.21-47.ELhugemem.debug
 
 Get rid of the System.map file, and then go find and put the
 /boot/vmlinux-2.4.21-47.ELhugemem file on the comand line. 
Thanks for the clue-by-four :-) I can now analyze the dump.
I was mislead because I got the same error using what I thought was a
standard "-g" kernel. It turns out a coworker put the kernel-debuginfo
vmlinux in our /linux/debug_kernels filesystem. That directory should only
contain kernels we've built from source with the -g switch; nothing else.
Grrrr.
