Haven't managed to get anything more than the beep out of mine, some day I 
might look at the vidc sound code.  No idea about the EagleM2 care.

No, You have 
8.3MB Active memory (pages that were accessed in some recent 
	interval)
7.1MB Inactive memory (pages allocated, but not accessed in 
	some recent interval.  These are good candidates for
	writing to swap if memory starts to get tight)
2.5MB Wired down (I think these are pages which cannot be
	swapped out because they are involved in some form 
	of I/O activity -- there may be other reasons, or 
	I may be wrong on this one).
11MB  Free (not allocated to something).

The above comes to about 29MB, leaving ~3MB for the kernel and its data 
space.

Additionally, you have
21MB of swap space used (processes which have had pages moved out to disk)
157MB of unused swap.

The last two should sum to your total swap space.

Did I answer that above?
