At least it works on Kurobox with this one:

0000:00:0c.0 IDE interface: Silicon Image, Inc. (formerly CMD Technology Inc) PCI0680 Ultra ATA-133 Host Controller (rev 02) (prog-if 85 [Master SecO PriO])
        Subsystem: Silicon Image, Inc. (formerly CMD Technology Inc) PCI0680 Ultra ATA-133 Host Controller

so, at least inprinciple, it might also work for you...

Don't know, maybe it's just generic PCI IDE support. Look at the "ide" 
command. u-boot supports ext2. To load a file from hda1 /boot, e.g.,

ext2load ide 0:1 <addr> boot/uImage

where "0" means hda, and :1 the first partition.
