problems with several saa7134 cards

I use several (from three to five) saa7134-based cards on single PC. Currently
I'm trying to migrate from 2.6.22 to 2.6.32 (ubuntu lts).

I've got problems which I did not have with 2.6.22 kernel:

1. Depending on configuration load average holds 1 or 2 when saa7134 module is loaded. The reason is kernel process "events/".

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
   16 root      20   0     0    0    0 S    3  0.0   9:36.89 events/1
   15 root      20   0     0    0    0 D    3  0.0   9:35.81 events/0

2. Sound and video are not synced when recording with mencoder.

The same problem with 2.6.36 kernel except "events" process have different name (can't remember exact name, sorry)

Probably, it is IR polling. You may disable IR via modprobe parameter:

$ modinfo saa7134|grep ir
parm:           disable_ir:disable infrared remote support (int)

Not sure if this parameter is on .32 kernel of if it were added on a newer one.

I think that there are some parameters at mencoder to adjust the sync between video and audio (-delay?). Basically, it needs to delay either audio or video, in order to sync. The delay time is empiric, as the audio API doesn't provide any way to pass audio timestamps, currently.
