   All device related, such as

   atarimouse, amigamouse, sunmouse, adbmouse, ...

Mmm, okay, that should be easy then: it's just like detecting ps/2
devices presumably, see below.

   I've a ps/2 on my powerpc. 

   Detection is hmmm ... not easy. How will you detect ps/2 versus serial mice
   on i386? 

Oh, *that* part is easy.  If you can open /dev/psaux then there is a
ps/2 mouse.  The kernel takes care of the device detection for you.

   And for your last question: for what will you use the 'virtual frambuffer device'
   on x11? It is not clear for me ...

Here's the idea: I don't have an Amiga, so if I were to write Amiga
framebuffer support for BOGL, I couldn't test it.  However, with BOGL
writing to a virtual framebuffer on /dev/fb0, I could then write an
X11 program to read the virtual framebuffer on /dev/fb0 and display it
in a window, thus allowing me to test it in at least a primitive way.
I was wondering if such an X11 program already existed.  (It probably
doesn't.)
