Unfortunately yes. My 12" iBook2 with 386MB RAM is a loosing power at
about the same rate.
Actually IIRC the 1GB of RAM are probably only worsening the problem
since the complete Gigabyte has to be kept under a certain current so
that it doesn't loose its content.
(I don't know if something is developed yet that can distinguish "used"
from unallocated RAM and powers of the latter when suspending).

Isn't the power-up time just long enough to get something to eat and
dring before starting to work? ;-)

I'm quite exited about the software suspend-to-disk in the coming
Linux 2.6 kernel which will save the RAM to disk and then completely
power off. The bootup time will then only be the time it takes to copy
the memory stored on the harddrive back to RAM (ok, plus kernel
initialisation).
I wonder why OS X doesn't have something similar in Panther with laptops
being a key market for Apple.
