Why on earth is this fairly recent motherboard using BIOS-88
to report available memory? I would have expected E820 here.
Can you send the dmesg output from 2.4.0 and/or 2.2.19pre7?

Different versions of gcc were used on 2.4.0 vs. 2.4.1.
Were different versions of as also used?  (hint?)

Or somehow in linux/arch/i386/boot/setup.S, your source
file has
#define STANDARD_MEMORY_BIOS_CALL
?

Your 2.4.1 kernel is really sick. According to this, your bios
does support E820 and 2.4.0 picks it up correctly. 2.4.1 for
some reason doesn't. I've looked through the 2.4.1 patch and
I cannot see anything which could cause this (the one memory
detection patch there only applies to the legacy bios-88 call).
Besides, 2.4.1 obviously works for the majority of users.

All I can suggest is to recompile 2.4.1 from pristine sources
(make mrproper or get a fresh tarball), using a known safe
compiler and absolutely no strange patches or CFLAGS overrides.

2.4.1 detects 64 MB, but 2.4.0 detects 192 (Maybe 191, not sure).

dmesg attached.
