Not that I see in the build trace. grepping:
gene@...ote:~/src/linux-3.2.40$ grep CONFIG_ATA .config
CONFIG_ATALK=m
# CONFIG_ATA_OVER_ETH is not set
CONFIG_ATA=y
# CONFIG_ATA_NONSTANDARD is not set
CONFIG_ATA_VERBOSE_ERROR=y
CONFIG_ATA_ACPI=y
CONFIG_ATA_SFF=y
CONFIG_ATA_BMDMA=y
# CONFIG_ATA_PIIX is not set
CONFIG_ATA_GENERIC=m

And it seems to be building libata:
gene@...ote:~/src/linux-3.2.40/drivers/ata$ ls -l|grep libata|grep .o
-rw-r--r-- 1 root root  10236 2014-02-10 18:19 libata-acpi.o
-rw-rw-r-- 1 gene gene 175870 2013-03-05 22:24 libata-core.c
-rw-r--r-- 1 root root  89616 2014-02-10 18:19 libata-core.o
-rw-r--r-- 1 root root  35904 2014-02-10 18:19 libata-eh.o

-rw-rw-r-- 1 gene gene  19559 2013-03-05 22:24 libata-transport.c
-rw-rw-r-- 1 gene gene    536 2013-03-05 22:24 libata-transport.h
-rw-r--r-- 1 root root  11772 2014-02-10 18:19 libata-transport.o

But libata.ko is not making it into the initrd, nor the modules.dep for 
3.2.40.

I been playing 20 monkeys changing one ata related thing at a time & doing 
a sudo time -p ./makeit to check, not much use rebooting to check until I 
see it.

I'll go gedit .config & change CONFIG_ATA to = m & try one more time.

Got it, test reboot time.  Made it 2 lines farther, "switching to clock 
source TSC" then fell through to the busybox prompt with all inputs dead.

Sigh.

.config attached if you've got time.

Thanks Randy

Cheers, Gene
