I suspect the Ubuntu kernel is lacking some of the very recent upstream patches that (maybe) resolve this issue.

Description of problem:
Fedora 9 use the "new" Real Time Clock Driver (Device Drivers ---> Real Time
Clock), but it don't work on HP DL380 G4/G5.
I don't know

How reproducible:
Install Fedora9 on HP DL380 G4/G5
Steps to Reproduce:
1. Just install Fedora9 on HP DL380 G4/G5
2.
3.
Actual results:
/dev/rtc0 won't be created.
Expected results:
/dev/rtc0 will be created and a symbolic link /dev/rtc will link to /dev/rtc0
Additional info:
It will work with "old" Real Time Clock driver,
(Device Drivers ---> Character devices ---> Enhanced Real Time Clock Support
(and Generic /dev/rtc emulation) ).
If "new" Real Time Clock Driver won't work on HP DL380 G4/G5 even in the future,
could you please compile the "old" Real Time Clock driver as module?
