1a1feb3827 change APM to use new almost-generalized BIOS trampoline: 
/*
 * void bioscall(int function, struct apmregs *regs):
 * 	call the BIOS interrupt "function" from real mode with
 *	registers as specified in "regs"
 *	(for the flags, though, only these flags are passed to the BIOS;
 *	the remainder come from the flags register at the time of the call:
 *	(PSL_C|PSL_PF|PSL_AF|PSL_Z|PSL_N|PSL_D|PSL_V)
 *
 *	Fills in *regs with registers as returned by BIOS.
 */

Thanks to Charles Hannum for complaining and inspiring me to hack this
together.

those by Poul-Henning Kamp <phk@data.fls.dk>) to get the kernel

when gcc1.39 is in use.)
