As mentioned in Auke's reply
I doubt 128mb will provide a pleasant experience...
I am actually trying on a device with 128 MB ram, UX is up on it but it almost
uses the entire 128MB memory even without any application being launched.
when I see the memory usage using 'top' command, the below is what I get
(sorted based on mem usage)

Above values are fairly useless. Please use something that reports PSS
and Swap usage (from SMAPS), for example:
http://www.selenic.com/smem/
Some examples of using above are here:
http://elinux.org/Using_smem_on_Android
Maemo has also SMAPS data based tools, for example this:
http://maemo.gitorious.org/maemo-tools/sp-memusage
(There's some documentation for maemo-tools in Fremantle SDK docs, but
that's somewhat out of date for the latest tools versions in git repo:
http://wiki.maemo.org/Documentation/devtools/maemo5
)
Or if you want more detailed information, use something based on
kernel pagemap information, like this:
http://git.itanic.dy.fi/?p=scan-pagemap;a=summary
(I have no idea whether above are already packaged for MeeGo.)
for now, MeeGo has 'memuse' in the repo's, I can see about adding smem
to the developer tools group, it's pretty small.
why are those top 5 process taking this much of memory?
I think it would be more appropriate to ask about this on
the meego-touch-dev list.
agreed
