Looks like the controller is not a separate PCI device. Toshiba provides Bus 
Mastering driver for Windows 95:
http://209.167.114.38/support/download/files_Archive/Index/windows_95_files.htm

So the controller probably can do DMA but it's not a standard IDE controller. 
And looks like there's no driver in the kernel for it.
