I have not tried booting into 2.4.x on FC3 at all. My early tests in FC2
(also 2.6.x based) when 2.6 was in no position to be used for audio were
not very successfull, there were too many (small) incompatibilities that
lead me to rule that out as an alternative early on in testing. 

Glad you are getting good results with the latest kernels! ... but see
other posts for other users that are not that happy :-(
