Okay. My wetware has been a bit overloaded of late. You observe from the listing that you have a reserved space from 3ff0000 to 4000000, which is the 64k just below the 64M boundary (the ACPI memory is available for reclaim.) mem=0x3ff0000 should give you the most possible memory.
What I don't understand--what I STILL don't understand, is why you need a command line option at all. The routines to initialize this memory should work just fine without any help.

Hi!

(We already talked about that machine. You remember: Toshiba satellite 4030CDT. But this time I've much better logs.)
I have to boot with mem=63M, otherwise it crashes at memtest. Here are boot messages:
