It probably has something to do with my firmware being so much older than yours. I need to get ahold of a CF to PCMCIA adapter that way I can flash mine up to 1.7.4 or something close to that. I tried just loading orinoco_cs and inserting the card. It looked like it was going to work but it panicked after about 3 minutes. Oh well, maybe I'll try to switch back to a stock rootfs if I can ever get Uboot to correctly recognize my internal drive in such a way that it will let me format it.
EDIT: I've got your newer rootfs downloading and I figured I'd go ahead and format. fdisk keeps segfaulting whenever I try to touch /dev/hda. Now I remember why I dropped pdaxrom way back when. I can't stand this uboot abomination lol.
