I've added to the bug 370159 this workaround for the hot plug function of SD Card reader and firewire:
adding to /boot/grub/menu.lst the string
"pciehp.pciehp_force=1"
(and eventually also "pciehp.pciehp_poll_mode=1", but for me the first option was enough). I added it directly at the end of the kernel 2.6.28, in the line starting with "kernel":
In the blog I read it was written to add this string after the commented line # defoptions=quiet splash but I didn't because I'm usually running the kernel 2.6.27 (that should manage pciehp as a module)
