I have the same problem with my T40p:
thinkpad_acpi: ThinkPad ACPI Extras v0.17
thinkpad_acpi: http://ibm-acpi.sf.net/
thinkpad_acpi: ThinkPad BIOS 1RETDRWW (3.23 ), EC 1RHT71WW-3.04
thinkpad_acpi: IBM ThinkPad T40p

Jan 21 00:15:01 ibm kernel: ACPI: ACPI Dock Station Driver
Jan 21 00:15:01 ibm kernel: ACPI: \_SB_.PCI0.IDE0.SCND.MSTR: found ejectable 
bay
Jan 21 00:15:01 ibm kernel: ACPI: \_SB_.PCI0.IDE0.SCND.MSTR: Adding notify 
handler
Jan 21 00:15:01 ibm kernel: ACPI: Error installing bay notify handler
Jan 21 00:15:01 ibm kernel: ACPI: Bay [\_SB_.PCI0.IDE0.SCND.MSTR] Added

When using the generic driver my thinkpad freezes when removing the cdrom 
drive. Hence, I switched back to the thinkpad-acpi bay code and it works.

Noooo! ;) Please fix the generic bay driver first. :)
