sorry for bumping the thread,

not bug but feature. seems a shame to have built in obsolesence from RH. also means "new" laptop i bought for the purpose of using 6 when it comes won't work even though it is several generations of cpu newer than my current CentOS5 laptop (pentium M 1.8GHz vs P3 700MHz). fedora 12 runs well but i can't abide the churn.
