I don't think so. I did most of the original CONFIG_ISA annotations
and I only added it to real ISA devices.
And the LPC devices in southbridges are normally not marked

There is great value. Basically most ISA drivers are not 64bit
clean (if they even still work on i386 which is also often doubtful
in 2.6) and it is a great way for 64bit archs to get rid of a lot
of not working code.
