Could you confirm that 0x01FF *doesn't* work, even if rtc support is
turned off?
[i'm currently compiling a 'minimal' kernel to see if I can track down
some other apm anomalies]

What BIOS is your laptop using (should be displayed in a message at boot;
my laptop reads 'Phoenix BIOS 4.05')?

No, see drivers/char/apm_bios.c, function apm_display_blank.
All APM-related options are restricted to the apm_bios.c file so that the
#defines at the top of apm_bios.c work as you would expect them to.
