I can confirm. Currently Chameleon detects MacOSX, Windows, FreeBSD but not Linux. :'(
By default, the bootloader for Linux is installed in the MBR/bootsector. During the Linux installation,
sometimes under advanced, you can choose to install grub(2) to the root partition, / of the Linux install.
I have SL and two partitions of Linux on my second drive. The last one, sdb5 shows up by default, and I
can boot that one or use F8 to show all choices and boot the other Linux, I think it's on sdb2. Either one
brings up the grub menu which is rather ugly, and I can choose either Linux install, SL 32 bit or 64 bit, or
WinXP or Win7 which are now on my first drive. I have an old Logitech webcam which only works under
WinXP, Win XP mode didn't work well. This way of installing Linux is standard for using other bootloaders.
