The motherboard is picky about kernels, now using a custom 2.6.15 ... Poor IDE support - required disabling write-cache with hpdarm -W0 /dev/hda
Drive model:
        Model Number:       Maxtor 91360U4
        Serial Number:      C40CYRLC
        Firmware Revision:  MA540RR0
Also, I'm currently using the nvidia driver instead of nvidiafb you've suggested (thanks for the tip!), and the madwifi Atheros driver for 168c001a.
