I have now build the hdspm driver from:
http://wiki.linuxproaudio.org/index.php/Driver:hdspm (2010-12-25)
and the hdspmixer (hdspmixer_64-1.9) from:
http://wiki.linuxproaudio.org/index.php/App:hdspmixer_64

I did this by copying the hdspm.c file to the (gentoo kernel)
/usr/src/linux-2.6.36-gentoo-r5/sound/pci/rme9652/hdspm.c
and the hdspm.h file to /usr/include/alsa/sound/hdspm.h and
/usr/include/sound/hdspm.h (had to change the include path for hdspm.h
in hdspm.c as well).

Both the driver and hdspmixer build fine.

There are some differences to the driver at:

http://git.alsa-project.org/?p=alsa-kernel.git;a=blob;f=include/sound/hdspm.h;h=81990b2bcc981bb4f31cae44616aa052c5f1066e;hb=HEAD
http://git.alsa-project.org/?p=alsa-kernel.git;a=blob;f=sound/pci/rme9652/hdspm.c;h=f5eadfc0672ab0073db93f8fe2b484069b42c814;hb=HEAD

At a quick glance I could see that Florian's name was missing in the
MODULE_AUTHOR section for example.

There is also one problem that I have with the driver and and MADIFace
plus a RME M-32 ADC (on a Macbook Pro running x86_64 Gentoo) - the boot
sequence hugs if I have the coax MADI input connected and switched on.
By toggeling to MADI optical during boot is boots fine and I can
afterwards switch back to coax after boot and the card and driver works
fine.
