qemu is unusable on my smp box

with latest qemu port (but i tried to downgrade it down to 
7.2.something and it didn't change), on a 6.1 host (see NEWLUXOR 
kernel config file attached), running a 6.1 freesbie image (see IPFW 
kernel config attached) qemu showed the following problems:

1) when i launch qemu, many times it goes directly to monitor and 
   sits there eating cpu (i've to manually kill it)

2) whenever it boots, i get a lot of 'calcru: going backwards...'
   (with or without kqemu loaded - no differences at all)

3) when i try to shutdown/reboot the freesbie image, it hangs
   after killing syslogd, and after around 15/20mins it starts
   syncing disks 

4) generally, whenevr it boots, it feels _really_ slow i.e. if
   i type a character there's a visible delay before it shows
   up in qemu window - unusable

all these problems occur on a dualcore pentiumd 920 (2.8Ghz),
2gb ram, intel 945g (X in vesa mode- agp doesn't attach) 
(see dmesg attached), while the exact same freesbie images runs 
fine on a 6.1 centrino at 1.6ghz 512mb ram and intel 915g (X with i810 
and dri).
Am i the only one to experience these problems?
Is anyone running qemu on a SMP host?
