Just a thought, the firmware level IDE driver is usually not using DMA
or any advanced reading methods, and as such a lot slower than the
according Linux driver. You might have a hard time keeping the 2s the
kernel needs.

Your calculation goes with 3+2+10s - Instead of tuning the 3s or 2s, you
might instead start improving on the biggest piece of the cake: the 10s.
I would assume the 2s kernel do some initialization that are expected to
happen for the suspend code to work. So even if you manage to win 2s
by not booting a kernel, you might have quite some other things to
"fix".
