patch vs 2.6.24-rc6 to increase PNP_MAX_PORT to 40

The 15 dmesg lines were presumably from the 39 - 24 = 15
IO resources here:

               Device (MBRD)
                {
                    Name (_HID, EisaId ("PNP0C02"))
                    Name (_UID, 0x1F)
                    Name (_CRS, ResourceTemplate ()
                    {
                        IO (Decode16,
                            0x0010,             // Range Minimum
                            0x0010,             // Range Maximum
                            0x01,               // Alignment
                            0x10,               // Length
                            )
                        IO (Decode16,
                            0x0024,             // Range Minimum
                            0x0024,             // Range Maximum
                            0x01,               // Alignment
                            0x02,               // Length
                            )
                            ....

Please confirm that this patch to up PNP_MAX_PORT to 40
makes the messages go away and causes no additional
issues on the Acer.

The alternatives to this patch are:
1. delete the message (and ignore the issue) like we did before 2.6.24
2. change pnp to use resource lists rather than arrays

I do not advocate #1 -- hiding a potentially serious problem
would be a mistake.  Rather, I'm inclined to ship this simple fix now
and look for #2 (a memory size optimization) in a future release.
