ASM hack: improved Gale Hairpin; please help

What about using an additional bit? $11D7/1 is used as part of the Earrings functionality, so it doesn't appear to actually be free, but it looks like there are two free bits on $11D9 (bits 5 and 6, between x2 GP and 'make body cold'), and $11D8/7 may be free as well.

I'll be the first to admit that I've only barely delved into this part of the code, but if it works it also offers the advantage of separating out the Initiative ability from the Gale Hairpin's existing preemptive attack boost, which probably makes it more appealing in a general sense.
