Hi
My K8T800 mobo resumes fine from suspend to ram with and without patch applied against 2.6.18. quirk_via_abnormal_poweroff makes some boards not boot 2.6.18, so IMO patch should go to head, 2.6.18.2 and everywhere "ACPI: ACPICA 20060623" has been applied.

---------------------------------------------------------------- Remove quirk_via_abnormal_poweroff
Obsoleted by "ACPI: ACPICA 20060623": <snip> Implemented support for "ignored" bits in the ACPI registers. According to the ACPI specification, these bits should be preserved when writing the registers via a read/modify/write cycle. There are 3 bits preserved in this manner: PM1_CONTROL[0] (SCI_EN), PM1_CONTROL[9], and PM1_STATUS[11]. http://bugzilla.kernel.org/show_bug.cgi?id=3691 </snip>
