In theory maybe, in practice no.
Testing with Wine 1.5.14 there's no change; the caps lock and reappearing settings window problems are still there. It looks like Wine's rawinput support isn't too great yet.
Part of the output on running winuae.exe -log (the 2nd line is printed by Wine):
Code:
RawInput enumeration..
fixme:win:GetRawInputDeviceList (pRawInputDeviceList=(nil), puiNumDevices=0x3f0f88c, cbSize=8) stub!
RAWINPUT: found 0 devices
