Subject: [PATCH] /drivers/ide/pci/piix.c kernel 2.6.23

In piix.c (and in ata_piix.c) are already included some patches to skip the cable check on some laptops and to enable UDMA>33 modes, but I've noticed than theese doesn't work on my Acer Aspire 5602WLMi (maybe exist more versions of this laptop). 
With this simple patch i can set transfert mode to UDMA100
