I'm not an OOorg power user - it's more a .doc/.xls viewer for me.

No "official flash" (which always everyone uses) but there is a free
replacement project somewhere which AFAIK works on 64bit. But I don't
know how good this (and I'm in no need for flash - I can live without
The few movies I want to look ran with one of mplayer, totem or xine

ACK - and since that software (also) needs to be fixed. Therefor I'm
counting this in practice as an non-issue.

Hmm, any better numbers on it (or links to places with them)?

On FC6 (IIRC) it took >80 i386 RPMS just to install OOorg.
The problem is not really the disk space for it (or the time and
resources OOorg needs to start) but that `yum upgrade` also pulls new
i386 packages which are not realy needed on the next update just because
the x86_64 version is upgraded. So unless you cleanup regularly you end
up with all of them (or you ignore "i386" in yum.conf and temporarily
add it if some dependency lib of OOorg wants to be updated - which is

That reminds me of a TYAN mainboard (Toledo i3100/S5207, Intel E6600 CPU
on it IIRC, Ubuntu + self-compiled kernel on it IIRC) bought in
March 2007 which ran fine with 4GB but didn't even boot with 8GB RAM
(and RAM is on their "recommend RAM" list for that board) and stopped
with an BIOS error not mentioned in the manual.
The third BIOS update - to a "beta" version - (since March) seems to
make it work now.
: It is not back online yes so I can't `ssh` into it.
: To be more exact: It booted 5 times completely without any
problems and then it stopped booting (when I was with at the
hosters place to put it onthe Internet, God I was fed up with
it and cursed it to hell!). So the "seems" needs probably some
time and several more reboots to generate more confidence.
