I had been getting the problem in previous versions of ubuntu on this Macbook 4.1. I was still getting them as of recently on Lucid. I followed a link from a launchpad bug report page (https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/400413) to a kernel bug tracker report page (https://bugzilla.kernel.org/show_bug.cgi?id=14718) and saw the suggestion to try booting with the kernel option 'irqpolled' enabled. So, I tried adding an entry for 2.6.32-24-generic with irqpoll enabled in grub.cfg, and since booting with that option, I haven't been having problems with sluggishness after suspend. But I wonder, why does changing the hardware interrupt type to polling fix the issue?
