What makes you think this is a kernel bug? Does this work in other
operating systems or kernel versions on this same hardware?

ACPI is a broad interface with hundreds of features which the system
firmware (BIOS) can *optionally* support. You should always enable
ACPI but it doesn't mean suspend to RAM will be possible.

No, there is no way to suspend to RAM on x86 without using ACPI
or (on old systems) APM. If the system firmware doesn't tell the
kernel suspend to RAM is possible, then it isn't.
