For what is worth, I have two such readers, which are working flawlessly 
with the ccid driver [1] and with 2048-bit keys. I have not tried them 
with the internal driver.

I also have a SCM 3500 reader from SCM Microsystems (now Identiv), again 
working flawlessly with the ccid driver.

Instead of watching the log, you could use a feature of Scdaemon: if the 
file $GNUPGHOME/scd-event exists and is executable, it will be called on 
every card reader status change.

For example, to act upon card removal, you could have the following:

   #!/bin/sh

   case "$8" in
   NOCARD)
       # do something
       ;;
   esac

See doc/examples/scd-event in GnuPG's source for more details of what 
this script can do.
