"From what I can see, gendev is a "pseudo" device that eats up unused
"iterrupt numbers.  I have deleted these things with no repercussions.

The gendev device is the frontend for the HPDD, and it catches all
interrupts destined for devices controlled by the HPDD.  Apparently you
have not reconfigured your kernel using kconfig after installation.
The installation kernel comes with five different controllers
configured, and each one takes a fair amount of time during the boot
process to decide that their card doesn't exist.  (They each take up
some kernel space and, as you've noticed, interrupts as well.)  So it
behooves you to run kconfig and "reconfigure the HPDD" after
installing.  BTW, interrupt 5 is used for the MCA MFM and ESDI cards.
