Why are you so fixed to crossbuildin?
Would it no be better, if we can get it natively?
(even if it build slower)

Since I build customized Packages for some customers, I run
into the same problem with i386, amd64, is64 and powerpc.

I am realy behind...

Rightm but if you buy the false Hardware, maybe the baseinstall of
Emdebian is working on it, but can you be sure, it can run Xorg with

Sometimes I have found realy curios problems where all is working fine
except ONE key-application.

Right, but since I do not need the power of a Sempron 2200+ (which is
my smalles machine) I can switch to a geode or somethin similar with
500MHz get much energy savings for the same Job I do in the Sempron.

I do not know, HOW heavy I use my Sempron 2200+ but I think, I use its
performance only to 10-20%.

Right, I need to decrease the size of my computers...
ONE MIDI-Tower can be replaced with 4-8 SBC's...

Today morning I have gotten the 2"5 Hitachi-Drives with 120 GByte
and the 3Ware 8500-8LP contoller.  This is only "BIG" computer
(PentiumM 800MHz) which will be my fileserver and it fit in a
µATX case...

Currently I fill TWO 42U 19"-Racks Which can never be mobile.

Using SBC's based on ARM, MIPS, Geode or PentiumM will reduce it
to a singel 20U Rack.

Right, but I need the combination of Emdebian and power saving.

Since I have gotten some PM's yesterday, it seems I am not alone with
the idea to live mobil... with the need for foll blown Mobil-Hardware
from Server to Workstations and communication systems...

I will buy I new GlobelSat System in form of a PCI-Card which is in
the same time a router and can be accessed like an VIA Ethernet
Interface.  It consumes only 36 Watt without the LNB...  My current
system 148 Watt (including LNB) using a 160cm Parabole.

Thanks, Greetings and nice Day
