If your BIOS can boot from a USB CD-ROM, you will be able to install 
FreeBSD with no problems.
All recent BIOS can - and even older ones actually. I have a couple of 
machines with 865G chipset (not exactly state of the art) and they boot 
just fine. The eeePC boots and installs fine from a USB CD.
Before the kernel (which also holds the drivers) is loaded, everything 
you need to read from disk / CD has to go through the BIOS at some 
point. After the kernel executes it will easily locate the CD (it will 
look like a SCSI CD-ROM in FreeBSD) and install from it.
As for making a dual boot system, there are of course various ways. 
Depends on what the other OS is. If you plan to dual boot with Windows 
Vista for example, I suggest you do not install the FreeBSD boot loader 
when asked, but instead to use a clever utility (EasyBCD) on the Windows 
side:

Quick and painless :)
