I think your problem is nothing to do with i586/i686 compatibility; IIRC 
Epia M10000's have Nehemiah cores, and so support the CMOV instruction 
and should be able to run i686 code.

[Technically all C3 processors are i686, but there's a bug in gcc which 
means that it takes i686 to mean CMOV is supported, when it's actually 
optional for i686 processors]

Random reboots often indicate failing hardware (and can be a right pain 
to diagnose).  Have you tried running memtest on your system for a few 
hours to see if it's the memory that's flaky?  And does anything show up 
in syslog that could give a clue as to what's causing the reboots.
