Please find attached patches that add the Adaptec 1420SA controller to 
the PCI ID list in the driver, and a small note in the kernel config 
option to state so.  This is untested as of currently, if anyone has a 
1420SA to try, that would be great..  The one I had access to is now 
gone to a remote location out of reach for testing.  I read in one post 
I found with google, that the 1420SA uses a 6541 chip instead of a 6041, 
but I am not able to verify this, and also don't know if it may still 
work as a 6041.  The card is still a Sata2, PCI-X card, with 4 ports, 
the same as the 6041 based cards.  This patch may or may not be 
useful..  The card comes with a manufacturer ID of 9005 according to a 
linux PCI-ID list, which is a secondary id of Adaptec's known as 
ADAPTEC2, and an actual PCI Id of 0241.
