As commented in the kernel bugzilla, the patch allows use of the SD card reader, but problems remain if a PCMCIA card is used. It is not clear to me whether the PCMCIA problem is there without the patch or not. At worst, the patch turns a "can't boot" problem into a "can't insert extra hardware" problem, which in my point of view is an improvement, but it's clearly far from optimal.
I would personally welcome the patched kernel going into the repositories. Other people may disagree.
Yes, this is still an issue on Jaunty.
