2.6.7, amd64: sata_sil not in /proc/scsi?

Hi folks,

I've got a mysterious effect breaking mkinitrd on my PC:

Even though sata_sil has been used to mount the root partition, there is no /proc/scsi/sata_sil. But on another PC, booting via aic7xxx, there is a /proc/scsi/aic7xxx.

I should mention that sata_sil is a module, while aic7xxx has been compiled into the kernel. But should this make a difference?

Regards

Harri
