No, PNP support is too new for the the mainline 2.4.x kernel, but you 
can get it in the -ac patches and it is probably included in others. For 
example, even a kernel as recent as 2.4.21-pre6 doesn't have PNP, but 
2.4.x-ac kernels have had it for about a year. Some vendor kernels may 
be patched for PNP but I don't know which ones. PNP doesn't really have 
anything to do with isa-pnp, and isa-pnp devices are obsolescent. Once 
you boot a kernel with PNP support you will have /proc/bus/pnp, and 
lspnp/setpnp will work fine.

I doubt that PS2.EXE will work under dosemu because of how it will want 
to frob the hardware directly. You can always boot off of a MSDOS floppy 
and then run PS2.EXE off of another floppy. Or if your FAT32 partition 
has a couple meg free you can put PS2.EXE and its associated files there 
and either make the partition bootable to MSDOS or boot off of a floppy. 
PS2.EXE runs slowly off of a floppy but it gets the job done eventually. 
PS2.EXE might run under native freedos but I haven't tried that.

There are a few things that PS2.EXE can do that aren't covered by setpnp 
or tpctl so you really can't avoid it. However all of the serial port 
settings can be read/set by lspnp/setpnp as long as your kernel has PNP 
support.
