The following may seem obvious, but here goes...
* remove unnecessary video cards, and drivers. Most colo machines
should do OK with just a text console running on the onboard GPU.
Dump all video driver stuff "/dev/agpgart (AGP Support)" and
"Direct Rendering Manager". This assumes you're not running X on
your colo machines. mc (Midnight Commander) is a great text-based
tool, along the lines of ye olde Norton Commander.
* disable sound cards/chips in BIOS and remove drivers and kernel
support.
* Run "rc-update show" and look for any services you don't need.
