Is it particular to 6.x *SMP* systems ?

I've been using 6.3-R with ULE for about a fortnight without any trouble (on a
pentium4-m UP).
I was drivent to switch to ULE because I suffered awful slow-downs, mouse
jerkiness and all: when compiling kernel or a port, for instance, mouse would
not respond with fluidity in firefox, switching tabs would take many seconds,
and watching TV with vlc showed many cut-offs and fixed pictures (not related to
network traffic or bandwidth limitations).
The transition to ULE made them disappear (still occasional mouse jerkiness
though).

I suppose the enhancements/corrections of 7.x ULE won't be MFC'd ?
