Short answer: No.

Longer answer: The kernel source (and hopefully it's documentation) should tell you what the kernel logs, but beyond the startup messages, that is really very little.  Each daemon running on your system should be able to create log entries somewhere, but each daemon must be treated as a seperate case.  Also, some interactive commands, and the shell (bash) itself can do logging.
You may have some luck by searching your distro's web page to see if they have anything describing their default logging.  You may also consider contacting your distro's support group directly to see if they maintain such a list.
You may also try searching on some of the security oriented mailing lists, or web sites, as logging would be a high priority for security.
   for example: http://tunelinux.pe.kr/security/lasg/logging/index.html or just http://tunelinux.pe.kr/security/lasg/

Some possibly helpful man pages:

keithh at hera:~> man -k syslog
Unix::Syslog (3pm)   - Perl interface to the UNIX syslog(3) calls
syslog-ng (8)        - logs system messages
syslog.conf (5)      - syslogd(8) configuration file
syslog (2)           - read and/or clear kernel message ring buffer; set console_loglevel
syslog-ng.conf (5)   - syslog-ng configuration file
syslog (3pm) [Sys::Syslog] - Perl interface to the UNIX syslog(3) calls
syslog (3)           - send messages to the system logger
/etc/syslog-ng/syslog-ng.conf (5) [syslog-ng.conf] - syslog-ng configuration file
syslogd (8)          - Linux system logging utilities.

keithh at hera:~> man -k klog
xchkdmp (8)          - dump the contents of a JFS fsck log file created with xchklog
klogconsole (8)      - Tells the kernel to what terminal it should copy messages
sysklogd (8)         - Linux system logging utilities.
xchklog (8)          - extract a log from the JFS fsck workspace into a file
klogd (8)            - Kernel Log Daemon

Not exactly related, but you may find this article interesting: http://equusasinus.com/lxa-paper/index.html

   I hope this helps.

Lost in Tokyo,
