Can anyone tell me why hwclock --directisa works on this laptop (Dell
Inspirion) but /dev/rtc does not (linux 2.6.21 from Debian sid)?
# hwclock --directisa --show

# hwclock --show
select() to /dev/rtc to wait for clock tick timed out

Is there a module udev isn't loading that it should be? Or do I need to
write a driver for it?
$ lsmod|grep rtc
rtc 12372 0
If you get no output, then the rtc driver has not loaded. But you don't
need to write one, try:
modprobe rtc
first. Then, if hwclock works, you may need to add the driver name to
the /etc/modules file.
Paul, if you use a Debian stock kernel, the rtc module is built by
default, and it should load automatically. Did you build your kernel
from the source?
