UPDATE This is no longer relevant since the availability of custom recovery.
DISCLAIMER I am not responsible for any damage you cause to your tablet with this.
Though I'd like to add simply dumping the ROM is expected to be harmless, as I've tried this many times over while developing and testing this.
What you will need:
If you do not want to dump your bootloader (easy):
After completing this procedure (the one for dumping bootloader) the SD card you used contains the following:
Sectors 0x200000 to 0x200400: Bootloader (u-boot.bin)
Sectors 0x200400 to 0x200800: Bootloader arguments (u-boot.arg)
Sectors 0x200800 to 0x204800: Recovery (recovery)
Sectors 0x204800 to 0x207800: Kernel (zImage)
Sectors 0x207800 to 0x209800: Boot logo (logo.bmp)

What you will need:
- An SD card. NOTE All data on this card will be erased.
- SD Card Reader.
If you do not want to dump your bootloader (easy):
- Take any SD card (256MiB+), format it using the HP USB format tool.
- Place the "utscript.sh" and "zImage.debug" files into your SD card.
- Place the "utscript" file from "nodump" folder into your SD card.
- You should now have 3 files in your SD card (and nothing else) - "utscript", "utscript.sh" and "zImage.debug".
- Safely unplug the SD card. Turn off your tablet, insert the SD card, hold Menu+Power.
- Wait for the process to complete.
- Remove the SD card. You may now turn on your tablet and use it normally. The backup is in the SD card. Plug it in and you'll see two new folders, "logs" and "dump". "dump" contains the various dumped files that you may put into an existing firmware (replacing each file) and logs contain information about the process.
- Take any SD card (2GiB+), and use a tool like SuSE Studio Image Writer to write the "mbr.raw" file (found in the "mbr" folder) to your SD card. Then safely unplug the SD card and then replug it back. Windows will ask to format the disk. Click 'No'. In My Computer you should see a 1GB external disk (this is expected), right click and format it.
- Place the "utscript.sh" and "zImage.debug" files into your SD card.
- Place the "utscript" file from "nanddump" folder if you have NAND ("mmcdump" folder if no NAND) into your SD card.
- You should now have 3 files in your SD card (and nothing else) - "utscript", "utscript.sh" and "zImage.debug".
- Safely unplug the SD card. Turn off your tablet, insert the SD card, hold Menu+Power.
