64-bit WINE worked for me. Even for running 32-bit WoW. (Though I was
running a multilib profile. Uncertain if that had an impact.)

IMO, it's worth the 'overhead' to run 64-bit, if only for the greater
number of GPRs and other architectural improvements. There's honestly
a lot of good stuff in x86-64 beyond the larger address space. The
increased address space also helps long-lived programs avoid address
space fragmentation.
