Re: [PATCH 2.6.22 2/4]S2IO: Removing MSI support from the driver

1.Removed MSI support from driver - unused feature

This is wrong.  pci_request_regions() grabs all the regions for the 
associated PCI device, which is the desired behavior.

Using request_mem_region() is not what you want to do for PCI devices.
