I've just checked full-history-linux. It came from this commit:

[PATCH] Complete support for PC-9800 sub-arch (9/9) SCSI

This is the patch to support NEC PC-9800 subarchitecture
against 2.5.65-ac4. (9/9)

SCSI host adapter support.
- BIOS parameter change for PC98.
- Add pc980155 driver for old PC98.
- wd33c93.c update error handler for eh_*.
- wd33c93.h register to int for PIO mode.

But the driver was removed again about on year later:

commit 36f51e495878ff38d639fe3109a6cbaba6c4f2be
Author: Linus Torvalds <torvalds(a)ppc970.osdl.org>
Date: Thu Jun 17 19:33:53 2004 -0700

This removes the files orphaned by the earlier PC9800 removal
