Both are 128 MB.  Strange.  And certainly Linux should boot in 128 MB.

If I boot with -m 512 I get this:
root@(none):~# free
              total       used       free     shared    buffers     cached
Mem:        378608      25196     353412          0       1012       8692
-/+ buffers/cache:      15492     363116
Swap:            0          0          0


so something is definitely eating a lot of memory (missing about 142M).
Same guest kernel/fs in qemu gets:
freeroot@(none):~# free
              total       used       free     shared    buffers     cached
Mem:        407080      23236     383844          0       1056       8692
-/+ buffers/cache:      13488     393592
Swap:            0          0          0

so it's missing about 114M.

I get 500MB with 2.6.31-rc1+.  What does dmesg say about the e820 map?
