Parport_pc module dependencies changed?

Recently (can't say exactly when) my printer and parallel Zip drive stopped working.

Turns out the reason is that the parport_pc module no longer loads automatically along with the parport and ppa modules.

Here's an excerpt (line-wrapped) from modules.dep:

/lib/modules/2.6.7-rc2/kernel/drivers/scsi/ppa.ko: /lib/modules/2.6.7-rc2/kernel/drivers/scsi/scsi_mod.ko /lib/mod ules/2.6.7-rc2/kernel/drivers/parport/parport.ko

/lib/modules/2.6.7-rc2/kernel/drivers/parport/parport_pc.ko: /lib/modules/2.6.7-rc2/kernel/drivers/parport/parport.ko

/lib/modules/2.6.7-rc2/kernel/drivers/parport/parport.ko:
<missing line for parport_pc.ko ??> <=================

/lib/modules/2.6.7-rc2/kernel/drivers/char/lp.ko: /lib/modules/2.6.7-rc2/kernel/drivers/parport/parport.ko

Seems like parport_pc.ko should appear as a dependency for parport.ko, but doesn't. (At least on on a PC, anyway.)
