Suspend to memory and Intel 8x0 soundcard

Hi,

While I am at it, I would like to report problems with this card, too:
Intel Corp. 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller.

Unlike the other guy's recently reported in bugzilla, mine doesn't resonate with motherboard, but rather severely drops volume. This happens after wakeup from "echo mem > /sys/power/state". At first I thought I have no sound at all, but after tuning everything to max I could hear some bits of Beethoven's 9th, with background noise of course.

The driver is unfortunately compiled in, so I cannot try re-loading module, but even swsusp2 reboot (proper BIOS init) fixes it (of course). Before recompiling kernel, I would like to know what all I cannot have hardwired into it for proper suspending (USB EHCI is for sure, ipw2100 I wouldn't put there anyway, Intel 8x0 sound seems to be next, FireWire OHCI1394 might have caused unhandled interrupt - see the other e-mail - list goes on... )

Please see my /proc/interrupts, /proc/version, dmesg and lspci -vvxxx in the other message, large attachments.
