It is no problem to get a sytem which fits into 16MB with a real (a little bit striped) glibc.
Here is the content of my /lib (about 4MB)

- Using uclibc and only busybox' stripped down sysv init
implementation lead to boot time of 35 sec on my 200MHz Pentium-MMX with a mostly static kernel (only module is lirc). Basic VDR's CPU utilization is at 10%. I found this impressive... 13secs is due to BIOS and grub.
20 seconds here.
