You could try to store the cs register into ds and es since with go32v2 cs =
ds = es. So little code like

movw %cs, %ax
movw %ax, %ds
movw %ax, %es

should be fine instead of the

movw %cs:our_ds, %ax
movw %ax, %ds
movw %ax, %es

etc. stuff.

This saves you the lock/unlock stuff for the v2prt0_ds_alias too.

Note that it may not work in the callback though it is probably worth a try.
