The visual mode started from insert mode with the mouse is actually "selection" mode, which is slightly different. Luckily you can map this "selection" mode separately from normal visual mode.

Visual mode: xmap, xnoremap
Selection mode: smap, snoremap
Both: vmap, vnoremap

:help select-mode-mapping
:help mapmode-x

Actually, using vmap and vnoremap is normally a mistake, since in selection mode pressing any key with a printable character will replace the selection with that character and drop into insert mode. I'm actually surprised that <Backspace> doesn't already delete the selection...I may map it to <Del> myself.

(I learned these things on this very list, by the way).
