The kernel probably doesn't have HIMEM enabled. I have 1GB RAM in my system. From my own running kernel, extracted from dmesg: [snip] BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009f800 (usable) BIOS-e820: 000000000009f800 - 00000000000a0000 (reserved) BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 000000003fff0000 (usable) BIOS-e820: 000000003fff0000 - 000000003fff3000 (ACPI NVS) BIOS-e820: 000000003fff3000 - 0000000040000000 (ACPI data) BIOS-e820: 00000000fec00000 - 00000000fec01000 (reserved) BIOS-e820: 00000000fee00000 - 00000000fee01000 (reserved) BIOS-e820: 00000000ffff0000 - 0000000100000000 (reserved) 127MB HIGHMEM available. 896MB LOWMEM available. found SMP MP-table at 000f5520 [snip] It looks like you are restricted to the LOWMEM limit.
