And we don't have a cursor I've noticed meanwhile. That would be very helpful for editing your linux cmd line in the boot loader. A blinking cursor is probably a bit unrealistic (need timer interrupt etc), but emulating a block cursor should be possible I think.
I was thinking something similar - just xor the character cell underneath the cursor. The only tricky part is to make sure to undo the cursor manipulation during any scrolls or screen writes.
I was also thinking about hooking the timer interrupt to support blinking, but like you, I concluded it wasn't worth the effort.
