How come the VBR isn't part of the context switch?


I guess that only user stuff is concerned by context switch.
A program manipulating supervisor stuff is probably not multitask friendly.

About sr, I guess that if it is fully saved among context switches, that's aside effect. I would bet that the original intent was only to save the CCRstatus bits, not IPL stuff, etc.

But of course, FreeMiNT is Free Software, so we are free to hack it for ourown needs :-)
