For this card reader to work on Acer laptops (that is the subject of this bug) we must force its unmask with the kernel parameter pciehp.pciehp_force=1 as Steven said (not force=0, that is counter productive), but then the computer won't suspend with a card mounted; to correct this follow the instructions found in the wiki page for the Aspire One: https://help.ubuntu.com/community/AspireOne/Ubuntu9.10, the Aspire One has a Jmicron card reader as well.

So the hack workaround exists, but it's a hack workaround in fact, I'm not expert enough to say wether it's the optimal solution. I've read somewhere that this card reader has power management that is lost with the force on option.
