When with option -icount,kernel message:
"HPET counter not counting. HPET disabled"

For the HPET please try this patch:
http://lists.nongnu.org/archive/html/qemu-devel/2011-11/msg01109.html

Maybe right,it is a ACPI issue.

I was actually talkin about the APIC one, but well, there are 24
anagrams of these letters (.

Sorry for that typo of last mail,What I mean is APIC not APCI. :)

I applied the patch: http://lists.nongnu.org/archive/html/qemu-devel/2011-11/msg01109.html.
But I feel it doesn't affect anything.

I am using QEMU-1.0 rc1,pulled on 9 Nov.
QEMU emulator version 0.15.91.

Then,
/usr/local/bin/qemu-system-x86_64 -enable-kvm -m 1024 -kernel vmlinuz-2.6.38-8-generic -append 'ro noapic=1 console=ttyS0' -serial stdio -icount auto

When bootup:
