Subject: [linux-audio-dev] hdsp+latency questions

hello everyone!

this is not exactly about audio-development, but the DRI+jack thread
encouraged me to ask a few questions about optimizing my setup:
i'm using a rme hdsp (cardbus) + multiface with my 1ghz pIII laptop for
quite a while now, and i'm happy with it.
i would like to use the setup for live-processing but the lowest jackd
framesize i can safely use is 2048. the main issue here seems to be the
nvidia graphics card.
since i switched from kernel 2.4.2x+lowlat+capabilities to 2.6.1 the
cpu-load seems to be noticable higher for ardour, but the latency-issue
did not change.
so my questions are:

*) is anybody successfully using hdsp-cardbus with really low latencies ?
*) how important is the firmware version - which firmware version should
i use for my hdsp card?
*) did anyone else notice increasing cpu load with audio-apps + kernel
2.6.x ?
*) any hints about configuring X11 for linux-audio (besides from DRI
questions ;-) ?

let me know if you think i'm on the wrong list should better alsa-dev.

thanks in advance
regards
d13b
