Ok, tried 2.6.26-rc9 today night - after disabling some drivers which
were not compilable and fixing some places in core code.  It does the
same thing - i.e. it locks up the same way as 2.6.25 did, and locks up
hard as before (no keyboard and network working).

Aha!.  That's very useful information, let me try just that... later
today, after work hours.  Added nmi_watchdog=1 and vga=0x5032 (in a
hope to see the whole thing on the screen) to 2.6.26pre lilo line...

Thanks!
