Hi Mike,
I really appreciate that you've clarified some of my mysteries. I am
going to put a note on linux.voyage.hk and this list for a update of
ALIX and mfgpt issue.
The problem right now is stock 2.6.24 includes a new mfgpt
implementation (I also port this code to 2.6.23-voyage kernel). If your
kernel compiled with GEODE_LX option, this kernel never boot even you
disable or enable mfgpt workaround option in tinyBIOS (>=v0.92). ONLY
v0.90 tinyBIOS can boot. Another options is to disable mfgpt in kernel
boot parameter "nomfgpt".
So this is what I've tested that 2.6.24 (or 2.6.23-voyage) kernel (with
GEODE_LX option) can boot on ALIX:
1. use tinyBIOS v0.90
2. specify "nomfgpt" in kernel boot parameter.
This new mfgpt implementation could be found in:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=arch/x86/kernel/mfgpt_32.c;h=0ab680f2d9db9af7885e9d5eedc9c02b79cd72d2;hb=HEAD

Hi.
Sorry for replying to my own mail, but I've just came across a related
pit-fall:
BIOS version workaround status
====================================================
0.93 and older not available
0.94 .. 0.98b always enabled
0.98c always off
0.98d .. 0.99 selectable, default: disabled
v0.98d seems to have a bug where the users' selection regarding the MFGPT
workaround is not saved properly to the flash. After leaving the setup the
BIOS will forget about the MFGPT reset option and will fall back on the
default (which is "MFGPT reset disabled").
Bye, Mike
