Sort of. It is a common "problem" that some BIOS are using parts of
the lower RAM as storage and the kernel just marks a certain area of the
memory as not usable to work around this. So your RAM is ok, your BIOS
just happens to be one that does use a bit of the lower memory but you
should be alright with that.

I have not have time to specifically work on this. However, all the changes
went upstream and into Karmic. Actually a few more. So you should definitely
try Karmic. Also, as we move ahead, things that are not really critical will
not get fixed in Jaunty. Even Karmic will receive a little less care as the
main effort goes into making the next LTS.
