The idea was that bits which are device-specific and which there would 
be no interest in sharing with other drivers in the kernel could stay in 
the VirtualBox coding style.  Since most updates to this code are likely 
to come from us and it is shared with our drivers for other platforms, 
that would make it easier for the in-kernel driver maintainer to pull 
fixes from the VirtualBox tree.  We tried to remove code from 
osindependent which would not fit that bill - notably, Hans reworked the 
driver to use a kernel gen_pool structure where it was previously using 
a VirtualBox-specific heap class.  My understanding is that something 
similar was considered to be acceptable for the new AMD driver code.  Of 
course, our code is much simpler than AMD's, so it would not be the end 
of the world if it were converted to kernel style, but I see more 
disadvantages than advantages to doing it.

Isn't dri-devel members only too?  My messages seem to take a while to 
show up there, which would be explained by waiting for a moderator, 
though I don't get a warning that the message is waiting for approval. 
For now we have disabled that on vbox-dev too (I assume that was the 
list you meant).
