The short form answer is yes and no. I have a mostly current EPIA cvs 
download,
that despite my best efforts at code tidying, continues to build and run every
now and again.

 From reading the thread here, it looks like you are getting to the 
bottom of the
  code in northbridge/via/vt8601/raminit.c

i'd suggest trying this

just before the

             print_err("vt8601 done.");

    line, add

             dumpnorth(north);

    and compare the register settings against the lspci -xxx -s 0:0.0

You may need to tweek your logging level to get output from dumpnorth.

The important registers are 0x64->0x66, 0x68, 0x69

I had similer troubles (hanging at vt8601 done) until i did this. Turned out I
had PC133 memory and the config was setting up for PC100

Depending on the values from the factory bios, you may need to alter the
definitions of DIMM_PC133 and DIMM_CL2 at the top of raminit.c to get you
going.


Mark.
