[coreboot] memtest86 reading 0k memory

All,

I have a board here that loads memtest86 but won't actually test memory.

This is the output:

       Memtest86+ v2.11
AMD K10 CPU @ 2312 MHz
L1 Cache:   64K  35028 MB/s
L2 Cache:  512K   6963 MB/s
L3 Cache: 2048K   6052 MB/s
Memory  :    0K 
|-------------------------------------------------
Chipset :




                          0K  LinuxBIOS



I'm guessing memtest86 doesn't understand coreboot's memory 
tables/structure, but I have no idea why that would be.  The e820 map is 
valid:
e820: BIOS-provided physical RAM map:
BIOS-e820: [mem 0x0000000000000000-0x000000000009fbff] usable
BIOS-e820: [mem 0x000000000009fc00-0x000000000009ffff] reserved
BIOS-e820: [mem 0x00000000000f0000-0x00000000000fffff] reserved
BIOS-e820: [mem 0x0000000000100000-0x000000003ffacfff] usable
BIOS-e820: [mem 0x000000003ffad000-0x000000003fffffff] reserved
BIOS-e820: [mem 0x00000000e0000000-0x00000000efffffff] reserved

Any ideas?  Other than this one irritating glitch coreboot is working 
perfectly on this board.

Thanks!
