Do you have this hardware and tested your patch?
I'm sure there is a reason, why "pci_disable_device()" was commented
out in the original submission in commit 681e14730c73c...

Additionally I'm wondering why your patch doesn't show up in
the fbdev patchwork, although you added linux-fbdev mailing list.
Probably a vger issue.
