Update of /cvsroot/src/sys/arch/i386/i386
In directory netbsd1:/var/slash-tmp/cvs-serv5102
(1) add a flag to the softc to indicate that the APM device may be
disabled even if it's attached. If disabled, ENXIO on open.
(2) in the case where the code32 segment len overflows the I/O hole,
instead of giving up truncate it. (In other words, revert
change (2) in rev 1.21 which i suggested mistakenly.)
(3) map bios data space in the 0->640k range with _i386_memio_map()
rather than with bus_space_map(), so that no accounting checks
are done. The checks which are done to make sure that allocation
in this range is safe are sufficient.
(4) check the return value from _i386_memio_map(), and if it indicates
an error disconnect from the APM BIOS, print an error message,
and return without having marked the device 'enabled'.
