You do not currently support scsi adaptors for laptops. You do not have adaptec 1460. (I have an external scsi hard drive on which I wanted to install linux unfortunately since you don't support laptop scsi I couldn't do it maybe in the next release you might want to include them,thanks.)
This adapter is indeed supported in the 6.1 installer. When you boot using the pcmcia.img disk with the adapter in the system, the card manager should automatically find the card and load the appropriate module for it. Reopen this bug if you are still having problems getting the installer to make use of your Adaptec 1460 card.
