My current setup is 3 500gb hard drives in a raid 5 array that is controlled by the Asus Commando Intel Matrix Storage Controller. I was wondering if it is possible to still setup a linux partition and install. Currently Vista is installed on the first 200gb, leaving 730gb for linux :). I understand that this is still technically a "software" raid and fully understand the performance issues, Im just wondering if its possible and if it is what device will the raid show up as under /dev?

This seems to be supported in the kernel using the dmraid driver. I don't know how current it is , but here is a place to start:

You may need to run 'dmraid -ay' before your devices show up in /dev/mapper after booting to the livecd. fdisk -l will also show all of the physical disks, but they will be sd* devices.
