Just tried on debian etc (2.6.13-rc6), two SCSI HDDs attached to an aic7xxx - same issue, independent if I use procfs or sysfs for device removal.

This unfortunately does not tell me if there is a pending reference to the device (e.g. due to mounted file systems). Such a reference would greatly help to satisfy my needs.
