Ok, here comes the first one. I chose this one because it fixes an actual
bug in the driver. This bug was (partially) introduced by myself when
porting to 2.6. Partly the reason was that I disliked using
function-like macros as lvalues:

sg_dma_address(x) = ...
sg_dma_len(x) = ...

[OT] wouldn't it be better to introduce some macros like
set_sg_dma_{address|len}(x, y)?

A part of the original patch has already been merged (s/UINT/ULONG/), so,
the actual version is re-diffed against 2.6.6-bk6 and re-tested (on a
plain Pentium).

Also updates the driver-version, printed on startup.
