which is necessary to work on 386 and 486.

Well, I applied the patch (in 2.6.23 it's
arch/i386/boot/pmjump.S,
not
arch/x86/boot/pmjump.S,
but that's minor) - still the same behavior, it still reboots
instantly right when bootloader gave control to the kernel.
So it must be something else.. ;)

Well, it's a good bet it's croaking somewhere in the setup code (arch/{i386,x86}/boot). Putting debugging statements there might help.
