hp dv8000t dead on resume from RAM

Howdy,

My hp dv8000t (core duo) is completely dead on resume from RAM (no caps
lock, sysrq, netconsole,
nothing). I've tried a recent (2.6.18-rc4) kernel running almost entirely
naked, so to speak (~990K) -- no support for:

SMP
preempt
modules
networking (+ enet drivers, unless running netconsole)
USB and SATA (not at same time; rootfs is either usb drive or SATA [ext2/3])
FireWire
cpufreq
framebuffer (vga=0)
audio
PCMCIA
IDE (for cdrom)

I've tried both native SATA (ahci) and legacy (ata_piix), but same result
w/both -- completely dead on resume from RAM. Blindly entering commands
does nothing, and running "$suspend ; $shutdown" does nothing either. I've
also tried with and without noapic, and a number of other kernel
paramaters, but nothing seems to work.

Be more than happy to try out patches, etc. to get this thing working.
Additionally, if someone could point me to that "beep on resume" patch,
that'd be great.

Some machine/debugging info (cpuinfo, messages, lspci, etc.) at:
