The patch is without problem on 2.4.13-ac7. Free memory increased by about 100K: free and dmesg both confirm 384292k vs 384196k. This is a P3-733 on an i815 with 384MB. Very nice.
Note that the patch and UP-APIC do not get along. Some quick debugging with William found the cause. APIC does indeed touch bootmem. The above is thus obviously with CONFIG_X86_UP_APIC unset.
