/dev/mem is gone!

["Brendan Thomas O'Connor" <brendano@stanford.edu>]

Hi all--

One day, I started up by Woody/Sarge machine, but X refuses to start:

(II) SAVAGE(0): initializing int10
(EE) SAVAGE(0): Cannot open /dev/mem
(--) SAVAGE(0): Chip: id 8c12, "Savage/IX-MV"
(--) SAVAGE(0): Engine: "MobileSavage"
(--) SAVAGE(0): mapping MMIO @ 0xf1000000 with size 0x80000

Fatal server error:
xf86MapVidMem: failed to open /dev/mem (No such file or directory)

$ ls /dev/mem
ls: /dev/mem: No such file or directory


MAKEDEV doesn't regenerate it, I'm not using devfs.  Where does /dev/mem come
from, and how do I get it back?

Thanks,
Brendan

p.s. cc me on reply if possible..

p.p.s more random info..
