Hi Martin,
Your test kernel eliminated the error message during kernel boot. But
"hwclock" still fails. :( I have attached 2 files:
rtcnew.log is the excerpt from syslog when your test kernel booted
strace.log is the "strace" output of "hwclock --test --debug" while
using your kernel
The "/dev/rtc" file does exist, as seen below:
gundam:~> ls -l /dev/rtc*
crw-rw---- 1 root root 10, 135 Mar 15 2002 /dev/rtc
gundam:~>
The "/proc/driver/rtc" file is also there:

During boot, I saw this error in syslog:
drivers/rtc/hctosys.c: unable to open rtc device (rtc0)
Consequently "hwclock --test --debug" would fail.
Can you please test the following kernel:
http://merkel.debian.org/~tbm/tmp/kernel/linux-image-2.6.26-2-r4k-ip22_2.6.26-18~test1_mips.deb
If it works, I'll put the fix into the next update of our 2.6.26
kernel.
