Greetings gentlemen,

please find the patch against 2.6.13 tree with Russel's proposal taken 
into account.
This patch that allows passing the pointer to custom power management 
routine (via platform_device) to 8250 serial driver.
Please note that the exported functions' API remained the same.
The only change for the outer worls is the format of platform data 
representation for the 8250 serial devices.

Best regards,
   Vitaly
