[Linux-parport] EPP modes

I would like to ask you a trivial question about the parport module, and maybe 
you could me point in the write address. The problem began because we have a 
device in our lab (haptic) that "needs" the EPP mode to run.

We have connected it to a Dell Optiplex (with Intel 945G chipset) , that the 
bios is claiming that it support EPP mode (and it's activated ..). However 
the parport module says:

parport0: PC-style at 0x378 (0x778), irq 7, using FIFO 

Looking on the web, the typical answer to this question have been always:
- if the driver doesn't show it is because it couldn't use it.

I have realised that all the boxes that we have here using 2.6.18 (debian 
kernel stock and 2.6.22) nones has EPP active. Also with kernels more recent. 
Also, only in a lab of 7 different boxes, only one could support EPP, when 
_ALL_  of them the bios claims to support it.

So my question are:
Is this a problem of the driver? This driver is unmaintained?

Thanks in advance,
