I'm not aware of any version of linux that installs or behaves
differently as regards write endurance on SSD's. i am not an expert
though, perhaps someone else on this list knows of one.
the linux kernel, starting with 2.6.33, knows about and uses the TRIM
command (http://en.wikipedia.org/wiki/TRIM_(SSD_command)), so you'll
want something with either a kernel at least that new or one with that
feature backported to it (backporting features like these is less
likely in my experience, outside of the redhat/centos world).
from some cursory googling on eeepc 900 and ssd write endurance, it
seems unlikely that you'll trip over write endurance actually being a
problem--for one, the drive in that machine is said to have 3%
capacity set aside for relocating failing sectors (which the
drive/controller handles independently of OS), plus be rated at either
10k or 100k writes per cell before failure. to hit 100k writes, you'd
have to write the same block 30x/day for 8 years (i stole all this
info from http://forum.eeeuser.com/viewtopic.php?id=25304, didn't
verify any of it).
everyone's different, but as a gambling man who likes good odds, i
wouldn't worry about the SSD failing in a way that you or even linux
will notice (automatic failure/relocation of sectors by the drive will
not be communicated even to the linux kernel). i don't know about
you, but my usage patterns aren't rewriting the same file over and
over again (or if i do, i am backing up my Magnum Opus frequently to
somewhere offsite). the worst offender on a system like the eeepc
will probably be swap if you run enough apps to have it swapping, but
these machines are slow enough without swapping that i went and bought
more ram as soon as i started hitting swap..it was cheap ($30) and now
i typically can run 2 VM's simultaneously (windows, so, bloated!) and
still have good interactive performance.
all that said, make frequent backups to another machine. frankly i'd
say loss/theft of the entire laptop, or operator error are more likely
causes of actual data loss.

depends on the machine/BIOS. in your case, it appears that is just about it:
