Config is fine, it's just make modules_install that's ignoring them.

With both 2.2.17 and 2.4.2, only with the patch, and it reports a c7 chip.
The only times it did get recognized the 16 Mb SanDisk CompactFlash card
(EC-16CF) was in the reader.  Though even that now doesn't seem to help 
anymore.  One clue only remains to be told: ever since installing the patch I 
get one error message lots of time: "invalid character 46 in exportstr for 
pd.drive0".  It's even printed at bootup from almost every init script.

It is in, and was in, I only had completely forgotten about that, never 
having had a need for it yet.

That, I figured.  Which is why I bothered the mailing list in the first 
place, so you know there are some issues with the patch as it is.

The only options I get in BIOS for my parallel port are Output-Only, 
Bi-Directional,  EPP and ECP.  ECP was the setting, and changing that to EPP 
and Bi_Directional only removed some of the protocols reported by the OS, so 
I'm back to ECP now.

I'll include a dmesg diff between one time he did recognize the thing and the 
current one:

Thanks for the reply, anyway,
