Hi!
I'm not sure if this is a bug or a feature. But in 2.6.9 cyclades.h have
different definition for struct cyclades_card. This definition uses
__iomem attribute which is defined in linux/compiler.h. This is not
included in cyclades.h, which leads to compilation problems for
util-linux package.

Well. All I know is that util-linux has cytune utility that does not
compile with 2.6.9 kernel headers. But compiles with older ones.

Here's the error message.

The first problem with linux/tqueue.h happens because during config it
tries to do it with only cyclades.h and fails on __iomem. So it decides
to include tqueue.h. Only to make things worse.
Here's the patch that I had to apply.

That works.
Can you send this patch to the util-linux maintainer?
