sd* at atapibus and 2200bg driver issues.

Hi,
on my dsm-g600 running netbsd-6 beta (daily 201204180900Z) when I plug
one of my external disks via USB this is the result (dmesg output):

umass0 at uhub2 port 1 configuration 1 interface 0
umass0: Myson Century, Inc. USB Mass Storage Device, rev 2.00/b0.07, addr 2
umass0: using ATAPI over Bulk-Only
atapibus0 at umass0: 2 targets
atapibus0 drive 0: <HITACHI_, DK23EA-40, 00K3> disk fixed not configured

Adding to kernel config file support for "sd at atapi" everything works fine:

sd*	at atapibus? drive ? flags 0x0000

Not sure that the flags configuration is correct, but after a lot of
tests I can confirm that the external drive works fine.
Please, could you consider to enable "sd at atapi" support on GENERIC?
Few weeks ago I started testing on my DSM a "new" wifi card, the intel
2200BG (iwi driver): I'm using my DSM as a client for a WPA2-PSK
network, with Ip4 static address.
When I try to send or receive via FTP a 20GB test file, the system
hangs. The number of bytes transferred may vary, is not a costant. No
kernel panic, no crash, both ethernet and wifi addresses are
unreacheable (no answer to ping) . If I try to shutdown my unit
pressing the power key, the shutdown seems to start, but not ends. If
I'm in shell via serial port and I try to run a command (like ls..),
the shell hangs and If I press <CTRL+T> this is what SIGINFO output
reports:

dsm-g600# ls
load: 0.07  cmd: ls 911 [biowait] 0.00u 0.03s 0% 1168k
load: 0.06  cmd: ls 911 [biowait] 0.00u 0.03s 0% 1168k
load: 0.06  cmd: ls 911 [biowait] 0.00u 0.03s 0% 1168k
load: 0.06  cmd: ls 911 [biowait] 0.00u 0.03s 0% 1168k
load: 0.02  cmd: ls 911 [biowait] 0.00u 0.03s 0% 1168k

No messages in /var/log/messages or on other logs.
This behaviour is a costant.
The only way to reset the box is the power plug...
There's a way to activate some kind of driver debugging?
I have tried defining IWI_DEBUG, but no results.
