OK, the directory exist.
But no libsane.fdi there.
It's elsewhere... see more below.

On my Hardy, there is a file called 20-libsane.fdi; the path is:
/usr/share/hal/fdi/preprobe/10osvendor/
and the 20-libsane.fdi file is +/- 210k great.

Content regarding LiDE25 is:

      <!-- Canon CanoScan LiDE25 -->
      <match key="usb.vendor_id" int="0x04a9">
        <match key="usb.product_id" int="0x2220">
          <append key="info.capabilities" type="strlist">scanner</append>
          <merge key="scanner.access_method" type="string">proprietary</merge>
        </match>
      </match>
 
</snip>

i don't know if that info should be relevant for resolving the problem.
