We should probably add a might_sleep() to ioremap() to prevent these

I think it is right to do this.
And it will be very useful to summarize common kernel interface
functions which may sleep into a list. When writing a new driver, the
developer can refer to this list to reduce or avoid sleep-in-atomic bugs.
This bug is eight years old. You can report it, but it's going to hard
to get anyone to fix it. I sometimes ignore ancient bugs. On the other
hand, netxen is fairly well supported so it doesn't hurt to try.
I try to report bugs as soon as they are introduced. I report it to
the author and CC the relevant list. If people don't respond to my
email after a month then I complain again.
