Damaged as the patch is, I was able to apply it by using
'patch -l' (ignore whitespace) + some fuzz.  Not something that
Linus or Andrew would or should do.

I built and booted the kernel, it's running fine (x86_32 notebook).

This is in the General setup menu.  How about putting it into the
EMBEDDED menu instead?  [Configure standard kernel features (for
small systems)]

There are still several build warnings that need attention:

drivers/acpi/sleep/main.c:223: warning: 'acpisleep_dmi_table' defined but not used
drivers/pnp/pnpbios/core.c:509: warning: 'pnpbios_dmi_table' defined but not used
arch/i386/pci/irq.c:1035: warning: 'pciirq_dmi_table' defined but not used
arch/i386/pci/common.c:148: warning: 'pciprobe_dmi_table' defined but not used


+#endif // CONFIG_DMI

Use /* ... */ style comments instead of // comments.
