Let's see, here is the line from my .conf file for ALSA sound on a 600E
(should be the same for a 600X):

options snd-card-cs4236 snd_index=0 snd_id="Card1" snd_port=0x530
snd_cport=0x538 snd_mpu_port=0x330 snd_fm_port=0x388 snd_sb_port=0x220
snd_irq=5 snd_dma1=1 snd_dma2=0 snd_isapnp=0 # snd_mpu_irq=9
snd_dma1_size=xxx snd_dma2_size=xxx snd_isapnp=0    

Note: I do not use the ISAPNP driver as it detects no PNP devices on the
ISA subbus...

BTW, these settings came from the IBM Thinkpad Readme.
