'fastboot' for i386?

does anyone have a patch that does booting without doing a soft reset?

in case no-one has done it yet ... what should be done? LILO itself
doesnt destroy the BIOS context, does it? If not, then is it enough to
reserve the first few KBs of the memory?

then an unclean but working and present protected mode -> real mode
switch and a jmp to some special address could start LILO again?

some hardware might get confused by this, but this should be just a
quick hack for the often-rebooters ... unfortunatelly my BIOS does an
SCSI reset even for soft reboots, which takes only a few but IMHO wasted
seconds :)

or maybe if some1 is sure that only the kernel >data< structures should
be updated, the kernel could go jump to start_kernel? This could be
signalled to sys_reboot? Some thinking has to be done to get the kernel
page tables right, but it's doable, isnt it?
