We have been working on this issue here at Dell and have determined it
to be a BIOS bug in its handling of USB. We should have this fix in the
next BIOS update (but I don't have a hard date on when that will be). In
the meantime, resolving the issue as outlined in Gary's bugzilla will
work; another option is to boot to rescue mode with RHEL 3 U5 CD1, and
edit the modules.conf file that way. If you only need PS/2 to work and
not USB, you can also turn off the USB controller in the BIOS setup
screen, and your PS/2 will work just fine.

I'll pass along more info about the BIOS fix as I receive it. 


Current workaround is:

Dell Precision 380 machines won't work right (will stop at the 'Starting
hotplug' at boot and not continue) with USB keyboards if ehci_hcd is loaded
after uhci_hcd.  Reversing the behaviour by manually loading them in
/etc/modules and listing them in the hotplug blacklist fixes the problem.

PS2 keyboard is unusable after usb is loaded.  This may be a problem with the
machines itself, however (buggy bios?).
