[flashrom] MX25L4005A with bus pirate

[Hugh]

I recent attempted to update the BIOS on my netbook and bricked it.  The
netbook uses a MX25L4005A<http://pdf1.alldatasheet.com/datasheet-pdf/view/267915/MCNIX/MX25L4005AM2C-12G.html>serial
flash chip and I have a Bus Pirate that I am trying to use to verify
that I can talk to the device in question.  I'm using the following command:

# ./flashrom -p buspiratespi:dev=/dev/ttyUSB0
flashrom v0.9.2-r1001 on Linux 2.6.35.7 (i686), built with libpci 3.0.0, GCC
4.4.3
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
Found chip "Generic unknown SPI chip (RDID)" (0 KB, SPI) at physical address
0x0.

This flash part has status NOT WORKING for operations: PROBE READ ERASE
WRITE
The test status of this chip may have been updated in the latest development
version of flashrom. If you are running the latest development version,
please email a report to flashrom at flashrom.org if any of the above
operations
work correctly for you with this flash part. Please include the flashrom
output with the additional -V option for all operations you tested (-V, -Vr,
-Vw, -VE), and mention which mainboard or programmer you tested.
Thanks for your help!

No operations were specified.

Running the same command multiple times with the -V option gives the
following lines for that flash device:

I'm using the following pin configuration:
  Bus MX25L4005AM2C
 Pirate Chip Chip  Pin Name Pin  CLK SCLK 6  MOSI SI 5  MISO SO 2  CS* CS# 1
+3.3V Hold# 7  +3.3V VCC 8  +3.3V WP# 3  Gnd Gnd 4
All power from the board has been removed (AC, Main Battery, CMOS Battery,
etc) and I have soldered in some 30ga wire to connect to the individual
pins.

I'm looking for any suggestions as to what I may be doing wrong.  If I need
to post this in the over on the Dangerous Prototypes forums, let me know.
Thanks!
