Yes.  The 2.4 kernels with low latency patch are better than 2.6 at
present (even the mm series).  The buffer sizes you can achieve are
dependent on so many different things (disks, FSB, memory,
configuration...) that there is no way to tell.  You just have to try it
and find out.  As far as minimizing buffer size is concerned - if you
are doing live audio or you want to monitor recording with inboard
effects turned on you need to have a small buffer size.  With the envy24
chipset cards you can use hardware monitoring so you can set the buffer
size to 2048 and have zero latency monitoring.  Don't confuse monitoring
latency with system latency.
