tmscsim broken on amd64 with 2.6.5?

[Christian Roessner <info@roessner-net.com>]

Hello,

I noticed that the tmscsim module seems to have problems with my DawiControl 
(2974??) and the TEAC CD writer. I told some people at 
linux-kernel@vger.kernel.org that the AM53C974 was the only driver that ever 
worked for me (2.4.x kernels). They said it was discussed here if to keep the 
driver in 2.6.x or not. They said the tmscsim would be preffered, so I send 
you some output with the hope you are able to fix it. A friend gave me an 
Adaptec 2940/UW, so I normally would not need to have this fixed, but I will 
wait and help you finding the error if you want to (Replacing the adapter 
later).
