Here is a cleaned up version of my 2.6.8 kernel patch.
This patch allows to use floppy drive in non-DMA mode on PegasosPPC and AmigaOne machines. To use it:
1. Do not build floppy driver as a module, link it statically. Transferring parameters to it from insmod is still problematic, at least it doesn't work properly on my system. May be i'll clean it up in future.
2. Specify floppy=nodma in kernel's arguments. Also you'll need to specify your drive type here using floppy=<Drive number>,<Drive type>,cmos. For example, floppy=0,4,cmos specifies type 4 (1.44 mb 3.5") for drive 0 on my system. Default drive type is 2.88 mb.
This patch does not affect operation of the driver in DMA mode so it's safe to use on any platform.
