fyi, I get around the issue by passing pciehp.pciehp_force=1 to the kernel at boot.

--as a test, if the above links help..
edit the GRUB boot menu

• esc (escape key) key
  --when you see the boot menus from grub; gets you into the grub mini editor on boot
• e
  --edit the boot line kernel line, something like this
• kernel /boot/vmlinuz-2.6.28-13-generic root=/dev/sda5 ro quiet splash
  change to
• kernel /boot/vmlinuz-2.6.28-13-generic root=/dev/sda5 ro quiet splash pciehp.pciehp_force=1

Have you tried running live from the usb port and installing to the built in card reader?
I can't see that it should make any difference though.

The only other thing I can think of is that you didn't install GRUB to the SD card you are installing to.

To repeat, I am using an EEE PC 701. At start, I press ESC and select my SD card reader. I cannot boot into Mint, so cannot get to any files to modify them from there

So..

• SD card works
  --you can read it on any other Linux OS,
• Mint cannot boot from the SD card

Well, last night I attempted to install to an SDHC card (generic Class 2 4GB) in the internal card reader from an SDHC card (Sandisk Class 6 4GB) in a Sandisk USB adapter. I went for the easy 'Use the entire disk' partition method and, at the last screen, hit the advanced button to make sure that the bootloader would also go onto the SDHC card.
Everything went as I expected and I now have a 4GB Class 2 SDHC Card with Mint installed on it.

I didn't have the issue of the drive showing up as a CD drive (do you get the CD icono n the desktop?) and my partitioning was different. That's it.

If you want separate root and home partitions, you could try partitioning the card as 5Gb for / , 10.5GB for /home and 0.5GB as swap.
Maybe try running Mint live from a regular USB drive instead of using a card reader and then installing to the SD drive.

To make changes permanent, edit the menu.1st file..

In the terminal

• sudo gedit /boot/grub/menu.1st
  --in a terminal
• gksudo gedit /boot/grub/menu.1st
  --on the desktop, via the gui..

--edit your changes and save the file
