My RHEL4.3 userspace broke hotplugging, because as of 2.6.29 there are two "sysfs" lines in /"proc/mounts". I fixed it in "/etc/hotplug/firmware.agent" by just assuming "/sys" as the "sysfs" mountpoint.

RHEL 5.3 in this case but it looks like the problem is in mkinitrd and
fixed already for later releases. For testing, I'm just going to build
the network module in and not worry about getting mkinitrd right on this
version of RHEL.
