Greetings,
Most likely, there is an undocumented register issue in the northbridge.
With the OEM BIOS, can you send me an lspci with a 400 FSB and a 533 FSB. That should narrow things down.

Greetings,
I'll have to do a bit of studying, but the one thing that jumps out at me immediatly is bit 7 of register 0x8c. and 0x78-0x7b. The big difference there is that DRAM timings are backed off a bit, and 0x8c selects for 133 (266) MHz operation.
There will likely be a bit of trial and error with differences to the RAM configuration since there is no way to dump those settings out (unless someone knows something I don't).
0xe8-9 and 0x80-3 are not documented by Intel. 0x80 appears to involve CAS latency according to Eric (it certainly seems that way). That setting is at line 189 of e7501/raminit.inc.
