Subject: [BUG] 2.6.23-rc1 broke APM

On this machine (Gigabyte mobo with i815EP chipset and a PIII),
APM worked fine up to 2.6.22. With 2.6.23-rc1 however the APM
driver fails to locate the APM bios:

--- dmesg-2.6.22	2007-07-23 14:07:46.000000000 +0200
+++ dmesg-2.6.23-rc1	2007-07-23 14:48:24.000000000 +0200

 Unpacking initramfs... done

-apm: BIOS version 1.2 Flags 0x07 (Driver version 1.16ac)
+apm: BIOS not found.
 io scheduler noop registered
 io scheduler anticipatory registered (default)
 io scheduler deadline registered

The only change in 2.6.23-rc1 to arch/i386/kernel/apm.c is a
trivial nofreeze flag removal, so I suspect the boot code changes,
perhaps the new arch/i386/boot/apm.c:query_apm_bios().
