Yup, since I wrote the code :-) The code in the distribution kernel only
has some small patches for the 53c400. There is a patch on sunsite and
mirrors which will give you interupts and pseudo dma. Although I'm pretty
sure you can get interupts out of the T130B without the patch. But get the
patch. It's a bit old and I'm planning to put out a 1.3.highnumber patch as
soon as I get a minute to think and I will also chase Drew up to
incorporate the patch into the kernel. I'm also working on completing the
work on that driver that Drew & I started to make it possible to use the
same driver almost invisible for the two cards.
