Re: cd record on an IBM T40p with Linux 2.6.9

You need to look at your grub config file for the append line for the kernel.  For ide-scsi to work there is a "hdc=ide-scsi" option on that line.  Your option may have something other than hdc.  If you remove that, it will never load the ide-scsi module and then you can use the ATAPI:0,0,0 type device to burn to.  Just for reference, you can not unload a kernel module that has already bound to a device.  That is why you got that message trying to unload the ide-scsi module.
