Thanks, disabling IDE worked.  It took a couple tries due to a Makefile 
issue (or misunderstanding on my part)... see below.  Now I get to 
figure out why my Gentoo userspace won't boot, which I think is beyond 
the scope of this list :)

NET: Registered protocol family 1
NET: Registered protocol family 17
drivers/rtc/hctosys.c: unable to open rtc device (rtc0)
linkstation: disarming the AVR watchdog:
kjournald starting.  Commit interval 5 seconds
EXT3-fs: mounted filesystem with ordered data mode.
VFS: Mounted root (ext3 filesystem) readonly.
Freeing unused kernel memory: 140k init
Synchronizing SCSI cache for disk sda:
Restarting system.


One issue I ran into is that "make zImage" does not rebuild an existing 
image, but "make uImage" does... I think the Makefile is missing a 
dependency.  I'll send a patch if I debug this further.  I know the 
"zImage" rule is just there for convenience, but apparently zImage is a 
deeply ingrained habit for me.
