you don't have any problem with pxe/syslinux, since your kernel already booted and
took over complete control on the system. Also syslinux doesn't do anything
in regard to APM.

So maybe your system doesn't have any apm bios (I've seen some laptops that
only have ACPI, and no APM any more), or has a buggy bios. Complain to your
vendor, or try using ACPI and see if this works better.

Regards,

Josef
