[hsflinux] problem with install on 2.6.4 system

[Robert E. Blair]

I'm running RHEL 3 with a custom 2.6.4 kernel (I need ACPI support and a 
custom software package that requires a module that is prebuilt).  When 
I try to install the hsfmodem rpm it fails (see below).  What are my 
options?

[root at pclap34 tmp]# rpm -Uvh hsfmodem-6.03.00lnxt04082400full-1.i386.rpm
