I think the >"25" in 386/25 means they use 25 wait states per memory access... FreeBSD should be able to handle it on your 25. As Bruce has tested, the sio drivers on FreeBSD will do 115K on a 16450 (Yes, that's correct) with about 90% CPU saturation on a lowly 386sx/16 (Again, that's what he wrote) With a 16550 it should handle it w/no problems.
