latest working acpi patches, are already included in kernel 2.6.9 since

In 2.6.9 you do not have to remove ehci_hcd or uhci_hcd anymore, they
resume successfully, add this hack (magic code *g*) to your bootloader conf:
in lilo: /etc/lilo.conf (acpi_sleep=s3_bios is the important thing)

image=/boot/vmlinuz-2.6.9
 append="apm=off acpi=on acpi_sleep=s3_bios resume2=swap:/dev/hdaX"
 label=his_Name
 read-only

dont forget to run lilo or so afterwards
