If you want to get some more possibly garbage data, you can set
forcewake from userspace, and hope the kernel doesn't unset it :).

intel_reg_write 0xa18c 1
# check for ack
intel_reg_read 0x130090

I've never tried it, but it might work at least for reading that first
bit. I'm currenty working around this with <1301105269-23970-1-git-send-email-ben at bwidawsk.net>
and a hack in the kernel to do a get() and never do a put.
