[hcflinux] Kernel panic on freshly-installed Fedora Core 6

That seems to have done the trick.  The system boots normally now and 
the fax server software is happy.

It's interesting that the HCF drivers worked fine with FC4 and its 4K 
stack kernels.  Such is the price of upgrades.

Thanks very much.
