corkyg, apparently the system won't boot, so firing up regedit on it might be difficult
I would be surprised if that registry location wasn't in system.dat.
I wonder whether you could grab system.dat, feed it to a newer Windows machine in regedit and tell it to import the hive. I'd consider doing it on a disposable Windows install or VM.
Failing that, I assume that regedit on Win9x can import from a registry hive file, so set up a VM running Win98 and give that a shot. My Win9x knowledge is understandably rusty
If you manage to import the registry hive in either case, then look for that relative location in the imported hive in regedit.
